It's just that having this debate is pure luxury already. Otherwise it'd be "where the hell do we get the gold we need to fuel our economy?" or "what do we do with all the surplus gold that's ruining our economy?".

Bitcoin, really? Private currencies where inflation is at the mercy of random developers who may or may not control significant currency reserves as well?

Using foreign currencies to supplant or replace a failed domestic currency isn't a new phenomenon, nor limited to "crypto""currencies" (the Balkans used the German Mark extensively in the late 90s, and US Dollars get you far in a lot of places).
