States can make it difficult and criminal to buy and sell crypto for fiat currency. It would probably end up working like drug prohibition, where drugs are still traded and used, but with one key difference: fiat currency is a superior alternative to crypto for almost every transaction a person makes, whereas the alternative to illegal drugs is substantially different (sobriety or alcohol). Crypto prohibition would have a far greater impact on its users than drug prohibition ever had, IMO.
