§7 Money and the State in Classical Economics

The global ledger answers “how to enforce rules,” not yet “what economic philosophy rules should obey”—classical economists argued that question for three hundred years.

Monetary questions run through three centuries of Western economic thought, from Smith’s awe at the efficiency of the division of labor, to Ricardo’s pursuit of the value of coinage, to Keynes’s rediscovery of effective demand, to the Austrian school’s distinctive understanding of monetary order—each generation wrestled with the same problem: whose is money, who governs it, and can it be deliberately managed? When blockchain protocols rebuild the technical base of monetary issuance, which classical presumptions long treated as natural laws do they unsettle?

Every major turn corresponds to an institutional crisis in the real world: Ricardo’s metallism answered post–Napoleonic inflation; Keynes’s demand management answered the Great Depression; Friedman’s monetarism answered stagflation; the Austrian theory of competing currencies answered the systemic failure of state monetary monopoly. Reading these crises against their intellectual responses clarifies blockchain protocols’ place in the history of monetary thought: they continue a continuous chain of intellectual exploration and technically supply rule verifiability that the paper-money era could scarcely achieve—whether institutional consequences cash out as particular answers must still be checked against observable metrics, not treated as a technological miracle descending from nowhere.

Section 1. Smith’s Logic of Division of Labor and the Origin of Money

Adam Smith opens Chapter 4, “Of the Origin and Use of Money,” Book I of The Wealth of Nations (1776), with the pin-factory story: ten workers in divided tasks can make nearly forty-eight thousand pins a day; if each completed the whole process alone, twenty pins a day would be hard to guarantee. The productivity leap from division of labor astonished Smith, but he immediately asked: division means each worker produces what he does not himself consume; all must exchange surplus for others’ surplus—what lubricates that exchange? Money thus enters Smith’s theoretical field: it is not wealth itself, but the medium that lets the division of labor keep running over wider geographic range.

Smith’s narrative of monetary origins has a distinctly evolutionary cast. In a barter state, people soon meet the harsh requirement of a “double coincidence of wants”: your fish must be what he wants for his cloth, and he must want fish—such coincidence grows rarer as population densifies and specialization deepens. Market participants therefore spontaneously converge on some generally accepted commodity—an “intermediate good” everyone will take even without direct use. Societies tried cattle, shells, iron, tobacco, salt; gold and silver finally won through durability, divisibility, portability, and resistance to decay. Carl Menger systematically argued the same logic in On the Origin of Money (1892): money is a spontaneous order that emerges when the most “saleable” commodity is selected through countless dispersed exchanges, not a product of state decree¹.

Worth close reading is that Smith did not credit monetary-value stability to state sovereignty. He distinguished “nominal price” from “real price”: real price is determined by the toil of labor expended in production; money is merely the measuring rod of labor. His attitude to Bank of England notes was conditional approval—so long as notes maintained metallic convertibility and were not overissued, they differed in essence little from coin and were more portable, favoring commerce. But once bankers, driven by profit, overissued, money turned from lubricant into destroyer. Government’s role should be to make and enforce rules against overissue, not to become the overissuer.

Here already lies a lasting tension: money is in essence a spontaneous market product, yet market operation also needs institutional guarantee of monetary rules. Smith did not systematically resolve that tension; successors extended it in different directions and finally split into metallists, quantity theorists, Keynesians, and Austrians—giving sharply different answers to the same question.

Chartalism approaches the same problem by another path. Knapp in The State Theory of Money (1905) and Innes in “What is Money?” (1913) argue that in the modern fiscal state, monetary value is primarily anchored in state acceptance of taxes and legal-tender commands, not in commodity saleableness rankings—“acceptance circles” are often first drawn by taxation and legal status; Mengerian emergence narratives better explain metallic-era origins than the everyday sanctity of today’s fiat². Goodhart summarizes the split as two concepts: M-money (market money of account) and C-money (state money of account): in modern fiat they overlay and coexist rather than mutually exclude—Zimbabwean and Argentine high inflation show that the C-money circle can maintain tax-nominal demand while M-money ranking has already shifted to the dollar³. This path does not mean to deny Menger’s archaeological narrative of the metallic age, yet it warns: on-chain verifiability can compress information costs of issuance rules without automatically expanding the acceptance circle—if protocol tokens have not entered the main loops of tax, wages, and public procurement, competition may long remain in edge corridors. Three intellectual-historical threads—Mengerian emergence, the chartalist state anchor, and Hayekian competition—must all be taken into the protocol era, not one chosen to the exclusion of others.

Section 2. Ricardo’s Metallism and Rules First

Ricardo followed Smith with a sharper stance on money. What drove him deep into monetary theory was a concrete policy crisis: during the Napoleonic Wars the British government needed continuing war finance; from 1797 the Bank of England suspended specie convertibility; note supply expanded sharply; sterling’s external exchange rate fell heavily; domestic prices rose. The episode sparked fierce public debate; Ricardo entered with The High Price of Bullion (1810) and related essays, becoming a leading voice of the “Currency School.”

Ricardo’s core claim: paper inflation is essentially a hidden tax levied by government on all money holders. Victims are creditors and workers holding fixed nominal assets; beneficiaries are debtors and issuers—especially government itself. This redistribution of wealth is completed through increase in money quantity rather than legislative procedure, thus needing no explicit parliamentary approval; monarchs and governments historically never resisted it.

Ricardo’s policy prescription was therefore extremely simple: money supply should follow predictable rules, not the discretion of bankers or politicians. The labor cost of gold mining supplied an objective benchmark for monetary value; metallic convertibility was the institutional chain constraining paper overissue. He supported the spirit of Peel’s Act (1844): requiring new Bank of England notes to be backed by equal specie reserves—in substance taking issuance power back from bankers and handing it to near-natural hard constraints.

Yet metallism has inherent fragilities Ricardo seems to have underestimated. The gold standard did provide price stability in normal times, but when financial panic swept, runs forced banks to contract credit, amplifying deflation and real collapse together. The British financial crises of 1847, 1857, and 1866 were each survived by suspending Peel’s Act and allowing excess note issue. The contradiction between rules and crises—the eternal game of elasticity and constraint—has no elegant exit in Ricardo’s system.

That contradiction reappears two centuries later in Bitcoin debates, with strikingly similar structure: a fixed issuance cap remains persuasive against inflation narratives, but when the macro environment needs elastic response, the cost of algorithmic rigidity is equally hard to dodge. Historical context changed; the structure of institutional tension remains the same.

Section 3. The Quantity Theory of Money: From Hume to Fisher

Long before Ricardo’s century, the Scottish philosopher David Hume had systematically stated the quantity theory’s basic proposition. In a 1752 essay he ran a thought experiment: suppose one night every Briton found five extra pounds under his pillow—he inferred no one would be truly richer; prices would merely double, because goods were unchanged while money chasing them had doubled. Money is a “veil,” altering only the nominal price scale, not the intrinsic ratios of real exchange—the earliest clear statement of so-called “monetary neutrality.”

Irving Fisher algebraized the proposition in The Purchasing Power of Money (1911), giving the famous equation of exchange: MV=PT. Money stock (M) times velocity (V) equals price level (P) times transactions (T). As an accounting identity the equation is logically airtight, but once auxiliary assumptions are added—“V stable in the short run, T determined by real production conditions”—it becomes a powerful policy proposition: control money stock and you control prices. The monetary authority’s duty thus emerges—it should manage money supply to prevent inflation from too much money chasing too few goods.

The quantity theory met Keynes’s fierce assault in the first half of the twentieth century and was restored in the middle and later decades by monetarism under Milton Friedman. Friedman’s contribution was not only to defend the quantity theory but to refine inflation from a vague social phenomenon into “too much money chasing too few goods.” A Monetary History of the United States (1963), coauthored with Anna Schwartz, supplied a new analytical frame for historical research: every major monetary contraction accompanied recession; the root cause of the 1929 Great Depression lay not in capitalism’s inherent defects but in the Federal Reserve’s allowing money supply to contract by one-third between 1930 and 1933⁴—over the same span U.S. nominal GDP fell from about $104 billion to $76 billion (1929–1933), and unemployment peaked near 25% in 1933⁵. That diagnosis overturned mainstream narratives of the Depression and founded Friedman’s influence for decades afterward.

The quantity theory itself does not directly support the existence of a central bank. Its most austere policy implication is: maintain predictable money-supply growth; no complex institution actively performing stabilization is required. Late in life Friedman repeatedly expressed distrust of the Fed, holding that central-bank discretionary disturbance often exceeded its stabilizing effect. Tension between the quantity theory and central-bank institutions in some measure runs through the entire twentieth-century monetary-policy debate.

The quantity theory also has an underestimated epistemological significance: it was the first major attempt to convert monetary-policy propositions from moral discourse into quantitative propositions testable by empirical data. Before Hume and Fisher, discussion of money was mainly normative—kings should not debase coin; governments should not overissue paper. Converting those judgments into “systematic relations between M growth and P change” was a step in economics’ establishment as a scientific discipline. That methodological importance is no less than its specific theoretical content—it founded the tradition of constraining monetary-policy discussion with quantitative evidence; on-chain protocols advance that tradition at the level of parameters publicly readable and historically replayable—whether that therefore beats central-bank discretion still depends on institutional adoption and observable results, not on the mere existence of code.

Section 4. The Keynesian Revolution: The Politicization of Money

When John Maynard Keynes published The General Theory of Employment, Interest and Money in 1936, the world economy had been mired in the Great Depression for over five years. Before idle factories and unemployment queues, the classical advice to wait for wages to fall automatically and markets to clear naturally had become politically and morally untenable. Keynes offered a sharply different diagnosis: the root was not wage rigidity but systematic deficiency of effective demand.

Keynes established the separation of saving and investment as the core clue to understanding fluctuations. In classical economics, saving automatically becomes investment; the interest rate is the price signal balancing the two. Keynes argued: when agents are broadly pessimistic about the future, even lower interest rates will not induce investment—expected demand is already weak; new capacity only deepens losses. More fundamentally, money has the “liquidity preference” Keynes systematically elaborated in Chapter 13 of The General Theory (1936): in uncertain times people choose to hoard money rather than spend; such collective behavior compresses effective demand and stalls the economy at a low-employment equilibrium, while market price mechanisms have no self-correcting power against it.

Monetary policy has inherent limits in this framework. When interest rates already near zero, further easing neither lowers real borrowing costs nor activates investment willingness—Keynes’s “liquidity trap.” In that case fiscal expansion—government spending directly, creating demand—becomes the only tool that can break the deadlock. Monetary and fiscal policy thus enter a framework of coordinated cooperation; their boundary becomes highly elastic.

The Keynesian revolution’s impact on monetary institutions was deep and lasting. It gave theoretical legitimacy to active government intervention, requiring the central bank to act as an active macro stabilizer in crises rather than a passive machine executing money-supply growth rules. Monetary-policy goals expanded from “maintain convertibility” gradually to “achieve full employment and price stability”—the appearance of a dual mandate means the central bank must make hard trade-offs, and those trade-offs are essentially political. Money was no longer a neutral veil but a policy tool that can be actively used to change real outcomes. That cognitive shift founded the intellectual basis for postwar decades of central-bank institutional expansion.

Since the late twentieth century, Woodford, Galí, and others have woven the Keynesian liquidity trap and Friedmanite expectation anchoring into a New Keynesian synthesis: downward rigidity of nominal wages and some prices makes moderately positive inflation (about 2%) welfare-superior and buffers the effective lower bound (ELB) constraint; flexible inflation targeting (FIT) then folds the employment gap into the central bank’s reaction function, claiming to internalize distributional concerns within a discretionary framework⁶. The DSGE benchmark models of Christiano–Eichenbaum–Evans (2005) and Smets–Wouters (2007) supply estimable impulse responses for this framework—lag paths of monetary-policy shocks on output and inflation became quantitative references for central-bank communication and forward guidance⁶. This framework is orthogonal to the protocol path: if FIT remains one of the optimal macro stabilizers within sovereign fiat systems, what is contested is whether mint participation rights must be closed, not wholesale denial of countercyclical tools. CBDC literature pushes the same tension back to the transmission side: Holston, Laubach, and Williams (2017) estimate advanced-economy natural rates $r^*$ fell from about 3%–4% in the 1980s to near zero in the 2010s; BIS (2023) cross-country summaries show $r^*$ highly sensitive to model specification—low-$r^*$ environments compress traditional rate-cut space, making Brunnermeier and Koby’s (2019) “reversal rate” and Bindseil’s (2020) tiered CBDC design companion issues for FIT in the ELB era, not macro stabilizers that protocol money can replace⁷.

Section 5. Friedman and Monetarism: Rules versus Discretion

Under the monetarist banner Friedman launched a systematic rebuttal of the postwar Keynesian discretionary tradition. His core proposition can be summarized: monetary policy’s lag runs from half a year to two years and is highly uncertain in length; under those conditions every central-bank attempt at “precise fine-tuning” is in fact a delayed response to a reality that has already changed, often pouring fuel rather than water. Discretion is not only useless; it actively manufactures fluctuations.

1970s stagflation—high inflation and high unemployment together, the Keynesian Phillips curve failing—became monetarism’s historical case. As early as 1968 Friedman had predicted that if government tried to buy employment with inflation, workers’ inflation expectations would adjust accordingly; real-wage falls would be offset by nominal-wage rises; the short-run “employment-for-inflation” trade would necessarily unravel in the medium and long run, leaving both worse. That prediction’s fulfillment is among the most powerful theoretical tests in twentieth-century monetary economics.

Friedman himself advocated constraining money growth by a “k% rule”—whatever the cycle, increase money supply by a fixed proportion each year (about 3%–5%). Not optimal strategy, but predictable and accountable, avoiding systematic bias from decision-makers’ subjective judgment. In his vision the central bank should not be seen as a clever macro-control machine but as an organization that must be strictly rule-constrained to prevent “good intentions doing harm.”

Yet Friedman’s monetarism also has historical limits: he advocated rules but accepted the central bank’s existence; he criticized discretion but believed that once institutions were well designed, the central bank could be an effective rule executor. He lacked Hayek’s radicalism—he did not advocate abolishing legal monopoly of money issue, still less imagine private or protocol-layer competing currencies⁸. Taylor (1993) operationalized Friedman-style rule preference as the Taylor rule—systematic reaction to inflation and output gaps—becoming the empirical benchmark of the New Keynesian “science” summarized by Clarida–Galí–Gertler⁹; Sargent–Wallace (1981) warned from the fiscal end: under high deficits, lasting low rates accommodating fiscal policy must eventually cash out debt dilution in higher inflation¹⁰. Leeper (1991) further formalized fiscal–monetary regime combinations: under “active fiscal, passive monetary” equilibrium, public-debt expansion is more likely cashed out in inflation than tax adjustment—aligned with the “ends of four big inflations” narrative Sargent (1982) summarized: ending hyperinflation often requires fiscal reform and monetary-anchor rebuilding together, not technical rules alone¹⁰. This is where he diverges from the Austrian tradition, and why his theory still has reference value in the protocol era but is not alone sufficient to prescribe protocol-era policy.

Section 6. Menger and Mises: Money as a Product of Market Process

The Austrian school takes Carl Menger as intellectual founder. Menger’s classic 1892 essay On the Origin of Money starts from a sharp proposition: money is not a product of state decree but a spontaneous order emerging from countless dispersed decisions of market participants. His argument path: everyone in barter has incentive to choose the most “saleable” commodity as intermediate medium of exchange—not because a king commands it, but because doing so lowers exchange friction and raises the probability of obtaining what one truly wants. As more people use the same commodity as intermediary, that commodity’s “moneyness” self-reinforces and finally, without any central coordination, evolves into generally accepted money.

The policy implication of this insight is more radical than it first appears. It means the state’s declaring something legal tender is not the source of monetary nature, but only ex post confirmation or forced solidification of what the market has already done. Money’s legitimacy comes from users’ voluntary acceptance, not political authority’s grant. If market participants have better substitutes, legal compulsion is the only means of maintaining monopoly—precisely what Hayek later proposed to break.

Ludwig von Mises greatly extended Austrian monetary theory in The Theory of Money and Credit (1912) and introduced analysis of monetary intervention’s dynamic consequences. The core insight of his business-cycle theory: when the central bank injects credit into the banking system at artificially low rates below market equilibrium, price signals received by producers and consumers are distorted—credit ease appears to mean abundant social saving, suitable for launching long-term capital-intensive projects. Mises characterized such expansion as prosperity driven by “circulation credit,” whose necessary end is liquidation of malinvestment and recession¹¹. Yet such “prosperity” rests on false saving signals; once credit expansion slows, true time preference is revealed and large volumes of malinvestment must be liquidated. Recession here is the endogenous result of artificial boom, not an exogenous shock.

Mises’s theory draws a fundamental critical boundary around monetary interventionism: the problem is not only whether the central bank’s technical operations are clever, but that the central bank’s existence itself necessarily introduces systematic distortion of price signals. Such distortion cannot be eliminated by more clever rule design; it is inherent in the act of concentrated decision intervening in the price process. The Austrian school therefore maintains deep suspicion of all forms of monetary sovereign intervention, whether the intervener is government, central bank, or international monetary organization.

Menger’s saleableness and Mises’s regression theorem: tension inside the Austrian school

Menger and Mises appear to share the Austrian tradition on monetary origins, yet there is a often-overlooked fissure. Menger’s 1892 argument almost does not rely on “nonmonetary use value”: people choose the most saleable commodity as medium because it is easiest to dispose of in exchange—attribute ranking (durable, divisible, broad demand) alone can drive emergence; state decree is only a later overlay¹. Mises in Chapter 8 of The Theory of Money and Credit requires: to explain today’s purchasing power, one must trace history back to a point when the thing was still demanded as an ordinary commodity; otherwise price formation is epistemologically “unanchored”¹². The regression theorem is thus a hermeneutic tool—answering “whence present prices”—not Mengerian selection dynamics—answering “what more easily becomes medium.” Kiyotaki and Wright’s search-theoretic monetary models supply a formalizable third language for this fissure: in random-matching economies, extrinsic saleableness (belief in wide acceptance as medium) alone can sustain monetary equilibrium even without industrial use—aligned with Mengerian ranking logic; but if one asks how first-day prices enter the exchange network, the regression theorem and “synthetic commodity” path must still answer the historical-anchor question¹³. White and Selgin’s 1994 Journal of Economic Literature dialogue adds a fourth question: even if saleableness solves medium selection, how does the unit of account converge among coexisting monies—whose price list prevailed in the private-banking era is the same class of difficulty as Bitcoin’s fifteen years of “strong store of value, weak unit of account”¹⁴.

Applying both at once to Bitcoin and on-chain tokens, tension appears immediately: the Mengerian path allows “saleableness ranking” to reopen on digital attributes (verifiable scarcity, global transfer); the regression path asks what priced the first day—if one insists on tracing to nonmonetary commodities, on-chain native assets forever “miss a link” in origin narrative. Wei Dai’s b-money (1998) and the Hashcash/timestamp chain embedded in Satoshi’s white paper §§1–4 supply engineering closure of “verifiable scarcity + distributed ledger,” yet do not automatically answer how Mengerian acceptance circles expand—Selgin’s “synthetic commodity money” (2015) tries to suture: replace metallic physical attributes with verifiable fixed supply and censorship resistance, so Bitcoin functionally meets the regression chain’s equivalent role without copying commodity history¹⁵¹⁶. Szabo in “Shelling Out” (2002) argues origins of monetary collaboration from prehistoric collectibles cooperation; in “Money, blockchains, and social scalability” (2017) he defines social scalability as the core metric of whether blockchain money can substitute interpersonal trust costs with verifiable rules—aligned with the “verifiability” dimension discussed in Chapters 6 and 20¹⁷. A more cautious reading distinguishes three questions: how zero-price starting points enter the first exchange (historical explanation); given an already formed quote network, what attributes maintain saleableness (ongoing competition); when multiple units coexist, how pricing and clearing coordinate (accounting convergence). Bitcoin’s fifteen years of market data answer ongoing competition while making historical explanation a continuing debate—more relevant to Hayek’s concern that “competition discovers discipline”: discipline comes from testable ongoing survival, not from waiting for full agreement on origin doctrine.

One can thus extend the Mengerian line: one core dimension of saleableness in the digital age is verifiability—whether rules and state can be third-party rechecked at low cost. This need not contradict the regression theorem, but warns not to use origin theorems to deny already running competitive processes; nor to use Mengerian emergence to bypass the hard problems of first-day pricing and ongoing pegs—overcollateralization and redemption mechanisms as white papers envision still await mainnet and stress-event tests, and cannot close pegs by appeal to “spontaneous acceptance” alone.

Free-banking historiography is likewise not a one-sided narrative. White and Selgin, from Scottish experience, stress that option clauses, clearinghouse networks, and discount clearing can endogenize discipline; Calomiris and Haber in Fragile by Design (2014) explain from political bargain: frequent early U.S. banking crises partly stemmed from states treating bank charters as political spoils and local financing tools, not from “competition itself necessarily degrading”¹⁸. Selgin’s 1986 “legal restrictions theory” asks: under layered branching bans, parity laws, and the 1865 holding tax, could markets display the Thiersian direction—reading three explanations together is closer to the sources than binary “free banking good/bad” camp-taking¹⁹. Rockoff and Rolnick–Weber’s quantitative studies further show: under no forced parity, the direction of bad notes discounting and good notes retained aligns with Thiers; once legislation bans discounting or forces face acceptance, the Gresham mechanism may re-embed in private systems. The two historiographical explanations are not mutually exclusive—they warn that the protocol era must ask simultaneously: can open access lower quality-authentication costs, and can on-chain governance avoid rules being captured by politics or capital. Technology lowering information costs is one thing; whether institutions move in the Thiersian direction remains a proposition.

Section 7. Hayek’s Competing-Currency Theory: Breakthrough and Limits

Hayek’s 1976 The Denationalization of Money offered in his later years the most radical concrete proposal on monetary institutions: abolish government’s legal monopoly of money issue; allow private institutions freely to issue their own named currencies; the public freely chooses among multiple currencies by purchasing-power stability. Good money—private monies that maintained stable value—would attract more users; bad money—those that overissued and depreciated—would be abandoned by the market. Competitive pressure forces every issuer to maintain purchasing-power discipline, just as competition in goods markets forces firms to maintain quality. The same cases can be read under three threads—chartalist sanctity peeling away, Thiersian M-money ranking, and limits of Hayekian competing currencies—cross-referenced with Chapter 5, Sections 1–2 and Chapter 2, Section 5 (Zimbabwe’s three readings), not choosing one to the exclusion of others²⁰.

Hayek explicitly acknowledged in the book that the scheme faced severe practical difficulties. The institutional-premise division of Thiers and Gresham is in Chapter 5²¹²². Competing-currency theory’s core tension: when multiple private monies coexist and the public cannot identify quality at low cost, spend bad, keep good can still appear; the trigger is authentication information asymmetry, not legal parity²³. Opening competition does not automatically equal low-information-cost competition; private issuers also lack a central-bank lender of last resort²⁴.

Hayek’s core claim: no central institution holds enough dispersed information to determine money quantity optimally; market dispersed competition is in principle superior to centralized decision, and the monetary domain is no exception²⁵. The institutional conditions he presupposed—issuers constrained by competition, the public able to monitor monetary quality in real time—were generally missing in the 1976 paper-money era; blockchain structurally fills the gap of “rules and state independently recheckable”: cryptography and consensus substitute for part of reputation constraint; open-source code substitutes for opaque bank promises; competitive units shift from banknotes to verifiable rule suites—this has intellectual kinship with Hayek’s question.

On-chain deployability and auditable collateral state do not equal retail and tax having switched to on-chain units (on-chain real-payment metrics in Chapter 1, Section 8)²⁶. El Salvador’s Chivo wallet 2022 survey found only about 12% of respondents used it regularly²⁷. Hayekian competition on-chain first appears as changes in rule verifiability and participation structure. Terra/UST’s 2022 zeroing shows: even with transparent rules, parity promises can still trigger death spirals in confidence crises.

Section 8. Classical Presumptions and Protocol-Era Propositions

From Smith to Hayek, three centuries of monetary intellectual history hide four nearly default implicit presumptions across schools—the intellectual foundation of traditional monetary institutions. Each time the protocol era loosens one, a new proposition and a data-testable implication correspond; together the four form the book’s main argumentative line. The book’s claim can be stated in one sentence: money will not be abolished; the state’s monopoly of the mint prerogative will—when bookkeeping, transfer, and issuance rules can be publicly verified at low cost, discipline against overissue shifts from issuer reputation toward protocol-verifiable rules. This chapter’s four presumptions then supply implications that can be checked item by item against data.

First presumption: money must be guaranteed by a trusted subject. Classical tradition rests acceptance on state, central bank, or private-bank balance sheets. The protocol-era proposition: overissue discipline need no longer rest entirely on the issuer’s person; rules themselves must be independently checkable by third parties. What data can test: on monies with higher rule verifiability, transmission from the same issuer-reputation shock to purchasing power should be weaker than for like instruments with opaque rules relying on institutional backing; if that difference is unobserved, the claim of “constraint-carrier shift” should be narrowed.

Second presumption: modification of monetary rules must go through political or legal procedure. The gold standard was established by legislation and abolished by legislation; central-bank policy goals are set by political decision and then empowered by legal frameworks. Hayek hoped competitive pressure would replace legislative constraint, but competition itself still operated inside national legal frameworks. The protocol-era proposition: some rules can be encoded as machine states default-immune to unilateral tampering, separating rules from persons; revision may still occur, but via auditable procedures such as on-chain governance, not closed-room discretion. If in protocols whose parameter changes require on-chain disclosure and timelock activation, frequency and amplitude of sudden policy turns still show no systematic difference from committee discretion, then institutional advantages of “rules embedded in code” are overestimated—governance-capture risks discussed in Chapter 13, Section 4 must enter evaluation.

Third presumption: cross-border monetary circulation depends on interstate coordination. Classical monetary analysis takes nation-state borders as implicit boundaries; balance-of-payments adjustment, exchange-rate management, cross-border clearing-message networks, and RTGS coordination are all engineering patches that presuppose national monetary sovereignty. The protocol-era proposition: value transfer can cross jurisdictions; physical borders become optional constraints—interoperability standards (such as VTP value-transfer protocol, IBC cross-chain communication) are designed to lower marginal costs of multi-unit coexistence so competition need not wait for sovereign coordination. World Bank 2023 data show global remittance average cost about 6.2%, with Sub-Saharan African corridors still often above 8%²⁸; Chainalysis’s 2024 Geography Report shows high-inflation economies such as Argentina and Turkey with significantly above-global-mean on-chain stablecoin receiving intensity²⁹. If on-chain adoption decouples from friction, then “protocols lower participation thresholds” must be re-explained with compliance interfaces, liquidity depth, and fiat on/off-ramps, not asserted a priori that monopoly is broken.

Fourth presumption: monetary stability is ultimately determined by the issuer’s incentive structure. Ricardo pinned hopes on metallic constraint; Keynes trusted institutional design; Friedman appealed to rules; Hayek bet on competition—four paths jointly assume that stability’s source is some constraint mechanism on human behavior. The protocol-era proposition: stability constraints can partly migrate to code’s deterministic execution and on-chain auditable state—collateral ratios, mint/redeem rules, supply caps need not depend entirely on “whether the issuer will self-discipline,” but partly on “whether rules are independently verified as executed.” PCIM (public overcollateralized issuance mechanism; Openverse instance VRC-10 + Bitgold) at the documentation layer adjusts collateral ratios by circulation-tier public votes, using redemption arbitrage and oracle circuit-breakers instead of MakerDAO-style liquidation/warning lines (upper tier near 161.8% collateral); this combination still awaits large-scale mainnet stress tests. Market repair speed after depeg or run should correlate positively with on-chain verifiability of collateral state, redemption queues (or liquidation queues in like CDP protocols), and supply curves; if repair speed correlates only with issuer PR or regulatory statements, then “verifiability” is insufficient as an independent discipline source—USDC’s brief 2023 depeg from Silicon Valley Bank exposure, with recovery speed related both to reserve disclosure and to federal intervention, shows that off-chain institutions still intervene above the “verifiable layer.”

Money endures; the mint prerogative can be dispersed; constraint shifts from reputation to verifiable rules—must be tested in high-friction scenes, not as an a priori conclusion. Classical economists asked the right questions: who issues money best? Rules or discretion? Competition or monopoly? Metallic anchor or managed float? Limited by tools of their age, they could not imagine protocol-era answers—especially silicon participants as economic agents needing no bank account. Actual evolution of monetary institutions is often driven more by war finance and election cycles than by academic optima; the gulf between theory and reality is a deep reason Hayek ultimately appealed to institutional competition rather than pure argument. Metallism, Keynesianism, monetarism, and Austrian competition theory, seemingly at odds, are all asking how to maintain balance between monetary convenience and power constraint.
