Just because Wozniak says it doesn't mean it's a fact. The entire issue isn't black and white, so it is debatable at best. Obviously, governments which decide to not welcome it has a different opinion. They either think it could cause an economic nightmare whose value is driven only by demand, or they think the fact that they can't control it can undermine their power in the long run.

Either way, I'm not entirely sure I agree that the monetary system needs changes, but if you have the chance to improve something, why won't you go for it? I don't know if the endgame of that is Bitcoin, but it for sure sparked the call for change.
