Sorry, I meant US dollars (the default reserve currency of the world), not Argentinian pesos. The occasional collapse of various small government currencies isn't really a statement on fiat currency, it's a statement on those particular small economies. For fiat currency to fail as a concept, the international reserve currency (USD for now) would have to fail.
