hmm, but they must also accept the crypto-currencies, the effort is in integrating any currency/card into the day to day. The same effort is required for cryptos, maybe less but still, quite a lot of effort. And countries will not integrate if they cannot earn from it, and in the end if they are controlled, there is no difference...

But this is already real, you could get cash from crypto in many countries around the world.
