Gold is very close therefore to the stone money of the Isle of Yap. This stone money, known as Rai, consists of large doughnut-shaped, carved disks, consisting usually of calcite, that can be up to 4 m (12 ft) in diameter, although most are much smaller. Apparently, the total stock of Rai cannot be augmented any further. It also depreciates very slowly. This intrinsically useless form of money in the Isle of Yap is in all essential respects equivalent to gold today in the wider world. Another example would be pet rocks, as long as the rock in question is rare and costly to get into its final shape.H/T: Thanks to B-Daddy for leaving a link in a comment that led me to Willem's outstanding blog.
Gold has become a fiat commodity or a fiat commodity currency, just as the US $, the euro, the pound sterling and the yen (and a couple of hundred other currencies) are fiat paper currencies. The main differences between them are that gold is very costly to produce, while the production of additional paper money has an extremely low marginal cost. If we count the deposits of commercial banks with the central banks, which together with currency in circulation make up the monetary base, as fiat money, then the incremental cost of fiat base money creation is zero.

Sticking it to the Goldbugs
... is just what Willem Buiter does in his most recent blog post where he takes issue with the whole concept that gold has real value.
