> Bitcoin fixes this kind of problem.

Not really, as long as everyone else you interact with uses fiat currency you need some way to convert between that and bitcoin which means you will be connected to the fiat financial system.

This problem might indeed be solved if the whole world moved to bitcoin, but that would introduce a whole host of other problems, most of which would be solved by reinventing banks and other parts of the financial system on top of bitcoin (note that these systems did exist already for centuries on top of gold and silver before the era of fiat money). Then you’re back to square one.
