Countries are accepting bitcoin already, but most of them only recognize civil right to property or commodity. The truth is, bitcoin is not some magical tool to solve world hunger or poverty but a tool for financial independence.
It is a good hedge but the effectiveness to overcome high cost of living is still questionable as there is only one country that has tried the hypothesis which is El Salvador and they seems to be doing fine.
If you want to buy bitcoin for a hedge, good. However, it doesn't mean you or any state that adopt it will automatically become rich or solve the financial problem they have, we need to acknowledge this fact.
Let's be realistic. The Bitcoin experiment in El Salvador has failed.
The people of El Salvador have refused to use it as a currency. Meanwhile, their economy has shown little to no significant progress since Bitcoin was integrated into it. As a result, they were forced to accept IMF terms in exchange for loans to save their struggling economies.
As you said, Bitcoin is a good risk hedging tool, but it is not a magic bullet to solve a country's economic problem. El Salvador is no exception.
