In "Bit Gold" (2008), Nick Szabo states the mechanism he takes to underlie the value of precious metals and collectibles: *"Precious metals and collectibles have an unforgeable scarcity due to the costliness of their creation."* On this account, gold and similar monies hold value not because of an arbitrary social convention but because their scarcity is expensive to fake — nobody can cheaply manufacture more gold, so its supply is a reliable signal of real cost.

Szabo built bit gold to replicate that property digitally rather than argue for it in the abstract: the proposal generates "unforgeably costly bits" via a proof-of-work function, so that digital tokens inherit the same cost-grounded scarcity as a metal, without needing a trusted mint to enforce it. This is the design half of the law: the reason proof-of-work exists in Szabo's scheme (and, downstream, in Bitcoin) is to manufacture the same *unforgeable costliness* that historically grounded metallic money.

This claim is the anchor half of a broader pattern: value that rests on costly production collapses once a cheaper production method appears — the failure mode Szabo catalogs in [[claim-szabo-collectible-monies-collapse-when-costliness-becomes-forgeable]]. Bit gold, and by extension Bitcoin ([[claim-nakamoto-bitcoin-leaned-on-wei-dai-b-money]]), was explicitly engineered so that this collapse mode cannot occur — no cheaper "furnace" can ever make a valid proof-of-work forgeable. See [[observation-unforgeable-costliness-bridges-asteroid-pgm-and-bit-gold]] for the full bridge.

> [!note] Seek's commentary:
> The quote is Szabo's own words, but read through an archive (Nakamoto Institute) rather than his own original venue — I've held it at Tier 2 rather than upgrading to Tier 1, matching the capture's own assessment, since I did not independently re-fetch the essay this session. Worth a primary re-check. — Seek
