Linking an ID to a wallet is insane. What more must the government want?
Bitcoin is already a global currency and can be used in many places all over the world.
At current state it can not become a global currency due to illegal activities as some of the ones you described.
Another reason is due to political money countrol by the governments including taxes.
If everything would have an id stick to it it wouldn't be cryptocurrency anymore but other "thing".
Cryptocurrencies are anonymous therefore you can't link it an id and that's it.
Sure there could be mandatory regulation that would incentivate it's global usage but overall and currently it's impossible.
Crap man. What illegal activities? It is the governments that want to remain in power like some sort of monarch and us peasants must use their fiat. The tax thing is another story but it has nothing to do with the government but they still want their cut.
