Paul Krugman has no concept of money as something that can be designed, but his argument on the social aspect of money can’t be ignored:

“The similarity to goldbug rhetoric isn’t a coincidence, since goldbugs and bitcoin enthusiasts — bitbugs? — tend to share both libertarian politics and the belief that governments are vastly abusing their power to print money. At the same time, it’s very peculiar, since bitcoins are in a sense the ultimate fiat currency, with a value conjured out of thin air. Gold’s value comes in part because it has nonmonetary uses, such as filling teeth and making jewelry; paper currencies have value because they’re backed by the power of the state, which defines them as legal tender and accepts them as payment for taxes. Bitcoins, however, derive their value, if any, purely from self-fulfilling prophecy, the belief that other people will accept them as payment.

However, let’s leave that strangeness on one side, along with the peculiar “mining” process — actually a process of complex calculation — used to add to the bitcoin stock. Instead, let’s focus on the two huge misconceptions — one practical, one philosophical — that underlie both goldbugism and bitbugism.

The practical misconception here — and it’s a big one — is the notion that we live in an era of wildly irresponsible money printing, with runaway inflation just around the corner. It’s true that the Federal Reserve and other central banks have greatly expanded their balance sheets — but they’ve done that explicitly as a temporary measure in response to economic crisis. I know, government officials are not to be trusted and all that, but the truth is that Ben Bernanke’s promises that his actions wouldn’t be inflationary have been vindicated year after year, while goldbugs’ dire warnings of inflation keep not coming true.

The philosophical misconception, however, seems to me to be even bigger. Goldbugs and bitbugs alike seem to long for a pristine monetary standard, untouched by human frailty. But that’s an impossible dream. Money is, as Paul Samuelson once declared, a “social contrivance,” not something that stands outside society. Even when people relied on gold and silver coins, what made those coins useful wasn’t the precious metals they contained, it was the expectation that other people would accept them as payment.

Actually, you’d expect the Winklevosses, of all people, to get this, because in a way money is like a social network, which is useful only to the extent that other people use it. But I guess some people are just bothered by the notion that money is a human thing, and want the benefits of the monetary network without the social part. Sorry, it can’t be done.”
