Money did not emerge from barter

The textbook account that money evolved out of barter — people swapping goods directly until the inconvenience of the "double coincidence of wants" forced them to invent a common medium — is contested. Decrypting Money takes the revisionist side: the barter-first story was promulgated without evidence by Adam Smith's The Wealth of Nations, there is little ethnographic evidence that a barter economy ever existed (much less that one evolved into a currency-based economy), and money "seems to have been an abstraction from the beginning" — a reading consistent with historical examples like rai stones, whose ownership transferred by declaration rather than physical exchange.

Nuance: the strongest version of each side should be kept apart from its caricature. The anthropological critique (associated with Mitchell Innes and later David Graeber) holds that credit, debt, and social ledgers predate coined money and that pure barter economies are unattested among societies studied ethnographically. The economist's defense is narrower than the caricature: barter demonstrably occurs where money breaks down (POW camps, hyperinflations — the book's own cigarette-money example), and the Smithian story can be read as a logical reconstruction of money's function rather than a literal history. The disagreement is partly about what "emerged from" means — historical sequence versus functional explanation. This entry rests on the owner's book notes; no external anthropological or economic primary source was opened for it.

Common misstatements: "Barter never happens" (it does, notably where currency fails; the contested claim is that a barter stage preceded money historically). "Smith documented barter economies" (the book's point is that he asserted the sequence without ethnographic evidence). "Money is only a state creation" — a separate chartalist claim that does not follow automatically from rejecting the barter origin story.
