Even if the governments ban or advice against the use of such, if people see value in what the coin offers, they'd use it still. Besides, if the coin is anonymous already, why would one be scared to use it and be caught? Anyway, I don't see governments easing their stance against such coins since it can be a vehicle to launder money anonymously. They can't just knock on the doorsteps of developers and force them to relay information as it can't be done. They will allow certain cryptocurrencies only if they know that they have a way to see how transactions are going, and with privacy coins, they are completely denied of that spying ability.
No one can stop if there would be still a community or people do support or make use of it but we cant really deny the fact that it would be hard if they would continue
to shut of the gateways on where a certain privacy coin user tend to make conversions but its not really that a big issue atm yet we have seen that these coins
do still manage to exist even though theyre are being gradually restricted.
