Bitcoin’s Achilles’ Heel
Bitcoin’s Achilles’ Heel Bitcoin’s Achilles’ Heel by Shanmuganathan N December 3, 2025 Indian Economy, Public Finance, World Economy While almost all market participants have an opinion on the value of Bitcoin, or the lack thereof, the most vocal proponents for both sides of the argument have come from the same ideological community of Laissez-faire Economists/Libertarians. To that extent, I will be drawing on the work of Rothbard, Menger, and Greenspan in this article. The objective is not to convert the Comrades or the Keynesians. Perhaps ironically, and to paraphrase Greenspan, “They (comrades/keynesians) seem to sense – perhaps more clearly and subtly than many consistent defenders of laissez-faire – that Bitcoin does not have the required monetary characteristics. And a restraining force on the reckless spending habits of government, it cannot be”. Trump, with his “Big, Beautiful Bill,” would not be embracing Bitcoin if it would. Let me start with the conclusions, and the rest of the article is a praxeological explanation of why it is indeed the case. Bitcoin’s Achilles’ Heel, as I have captioned it, is not the lack of widespread adoption as a monetary medium, as one might expect. It is the lack of any non-monetary utility whatsoever that disqualifies its usage as a monetary medium. Even if Bitcoin is adopted by a few countries as a medium of exchange, either through legal tender laws or by the willing use of market participants, it would ultimately fail the test of “desirability.” The Origins of Money The society transitioned from a direct exchange (barter) to an indirect one (using a medium of exchange), as it was more efficient from a transactional standpoint. It permitted greater, easier, and granular exchanges as compared to the prevailing barter system. Consequently, the division of labour could be greater when the medium of exchange was more “marketable” as compared to direct exchanges. The entire process did not originate through an overnight discovery, but a gradual transition of members accepting and using the medium of exchange for conducting their transactions. This medium of exchange had to be a highly valued good under the barter system before it became accepted for its monetary value in indirect exchanges. Or, in other words, the monetary property of a commodity was a consequence of widespread non-monetary utility within a community. It couldn’t have been otherwise. Many textbooks would define money as a “medium of exchange” and a “store of value” (i.e., retains purchasing power). However, as readers would realize, a good medium of exchange would also be a store of value. Greenspan summarizes it best in terms of the advantages of moving from a barter system to using money as a mechanism for conducting transactions. Reproducing his quote from Gold and Economic Freedom, “The existence of such a commodity is a precondition of a division of labor economy. If men did not have some commodity of objective value which was generally acceptable as money, they would have to resort to primitive barter or be forced to live on self-sufficient farms and forgo the inestimable advantages of specialization. If men had no means to store value, i.e., to save, neither long-range planning nor exchange would be possible.” While all commodities possess varying degrees of acceptability as a monetary medium, it was the non-monetary utility that determined their widespread market acceptance for monetary purposes. Literally hundreds of commodities have been experimented with as a medium of exchange in the free markets, and only three have met the market test across countries and for extended periods of time. This is depicted in the table below. So, why did society start using wheat as a medium of exchange and subsequently transition to iron/copper, and eventually gold/silver? Once again, we turn to Greenspan for a pithy summarization “…the commodity chosen as a medium must be a luxury. Human desires for luxuries are unlimited and, therefore, luxury goods are always in demand and will always be acceptable. Wheat is a luxury in underfed civilizations, but not in a prosperous society. Cigarettes ordinarily would not serve as money, but they did in post-World War II Europe, where they were considered a luxury. The term “luxury good” implies scarcity and high unit value. Having a high unit value, such a good is easily portable; for instance, an ounce of gold is worth a half-ton of pig iron.” So not only should the object used as a medium of exchange have widespread non-monetary utility, but it should be a very highly desired commodity as well. The transitions over thousands of years reflect this, as increasing productivity, induced by the specialization of labour, turned what were once luxury items (e.g., wheat, iron, and copper) into basic, everyday goods. Why only Gold / Silver? While societies have experimented with hundreds of commodities, we eventually settled on gold/silver, as they best met the requirements desired of money. The authors mentioned in the beginning (Rothbard, Menger, and Greenspan) have extensively documented the rationale, and a summary table is included below. While desirability (i.e., a luxury good on account of its non-monetary utility) has been expanded earlier, a brief overview of the other four properties is provided below: Durable: An ability to retain its essential property over prolonged periods of time. Gold and Silver, even under the most corrosive conditions (e.g., the ocean floor), retain their essential properties over thousands of years. While proponents have argued that bitcoin is durable (as it is nothing more than an algorithmic token), durability refers to not merely the extended physical/virtual existence but the continued desirability of the object over that time period. Even assuming some non-monetary utility (i.e., desirability) is found for bitcoin in the years ahead, how can we remotely suppose that a better algorithm will not come along that will serve the same purpose better than bitcoin? Divisible: An ability to subdivide into tiny units, with the divided unit retaining its fractional value of the whole. While gold can be divided into units of 0.001 gram with the unit retaining its value by
