Good thing no government or bank would ever want it to be like this, as the first couple years of the free market deciding would most likely be a a good deal of chaos (and I'm not saying if that's a bad or good thing, I'm just stating it)\
Government and politicians are always going to want control of monetary policy, and while it does make sense, that blockade makes it pretty much impossible for the free market to decide on currency usage.
Governments don't have control of the free market. If something is a good idea then it will catch on. That's what I like about bitcoin -- or crypto in general. It gives you an option to the mainstream and something that is outside of state control. When they control the fiat supply they can do what they want with it and that's why it's constantly being devalued.
They certainly want to such control...
