Bitcoin does solve it (or, rather, people holding their savings themselves instead of lending them to a centralized intermediary does solve it). When everyone's savings are in the bank, you only have to use the $5 wrench on a single bank executive to take a million people's money. When everyone's savings are in their own possession, you have to use a million $5 wrenches on a million people, one at a time, to take their money, and you don't initially know which of those people has how much money.

I mean, yes, the government can still probably take your money, or for that matter kill you with impunity. But it's a good idea to put some obstacles in their way that aren't merely procedural.
