You've now expanded your argument a lot further than original. I'm not a bitcoin hoarder so I won't try to defend that approach. Your original comment said that he was living off dollars, as though they are equivalent, which I don't think they are. You are right that until bitcoins can be spent directly for goods you are limited. Dollars are not the only thing you can trade them for. If you piss off the US government, they have to work very hard to shut down every exchange in every country in the world. I don't think it's a rock solid plan, but it's not just "living off dollars".
