Even in the most totalitarian regimes there are black markets, so it's not totally hopeless, but they won't make it easy to dump digital dollars.
Of course. Bitcoin will be the currency for underground markets. I already started something like that around me. Is not perfect, but in case of "disaster" people are prepared and they know what should do. Now we are just playing around and testing. But I am not sure if many are prepared like that, with a minimum local community trading in BTC.
