Excerpt from a Paul Krugman Bitcoin reality check

"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."
