I think the issue is that you are speaking from a position of comfort from the US. Of course USD seems fine to you, the US suffers the least in all these recessions. But for people outside the US, they often see their entire life's savings vanish. In Argentina inflation is not something that is only academically talked about, it has a real effect on every day life, the government understands this (and exploits it), and thus works hard to prevent everyone from fleeing the currency. Bitcoin does offer a real new alternative in this regard. Whether it will prove to be any better is admittedly an open question, but the idea that USD is some saving grace for foreigners is naive.
