Of course not: if you are fined heavily if you use them, most people won't use them and that's it. Follow the crypto through the chain and if it seems to originate from you, you pay 100x whatever is in the address. Or jail if you cannot pay that. Would work no? You do not need technical measures if you are a resident of a country. But you catch them at the point of conversion to fiat. And then it becomes too much risk and hassle. I think it would weaponize blockchain: the fact you can be lifted from your bed in 20 years for an illegal transaction because it is on the chain would be enough for most to never touch it.
