I think your arguments make sense when focusing on the US, but I don't necessarily agree that "mass adoption" would have to include the US. If bitcoin were mad

I think your arguments make sense when focusing on the US, but I don't necessarily agree that "mass adoption" would have to include the US. If bitcoin were made illegal (or impotent by regulations) in the US, bitcoin wouldn't die-- we'd just get left behind in terms of innovation; financial and otherwise. As an American, I'm hoping that doesn't happen.
