In the way you think, authoritarian countries won't have any cryptocurrency that could be used eligible?
Government won't allow us (citizens) to use cryptocurrency, to buy smth in supermarket and pay crypto for that. There will be a very huge war between government, or we should change todays government (usually 50+y.o. people that will never understand cryptocurrency) to young generation.
I think that something like a war against cryptocurrencies is going to happen but governments are going to lose and the reason is simple, how are they going to regulate a market that was designed specifically to avoid regulation? How are they going to avoid that people use it when they have no control over it? When it comes to their fiat they have complete control and so you have to comply but when it comes to bitcoin they cannot control the network.
In fact, not everything is as simple as it seems at first glance. Only transactions between citizens can remain secret from the state. However, the purchase, exchange and sale of crypto-currency in other cases may be known to the state and then it through the crypto-currency will be able to control the financial activity of citizens. Under these operations, the state will force people to leave their data and our anonymity will practically disappear.
