> Properly designed cryptosystems produce ciphertext that is indistinguishable from a random number. It's also impossible to tell from a 100 dollar bill if it has been taxed or not, yet taxes are enforceable. Almost no law enforcement relies on physically preventing something from existing, especially in any kind of automated manner. So yes, they can't stop people from possessing private keys that correspond to wallets, or whatever, but they can stop banks from working with crypto related business, force google to block results, force ISPs to take down crypto sites, block any kind of crypto app from both app stores, etc etc. Even block foreign sites. Not to mention, jail people who touch crypto. Not saying they will or that they should, but "crypto is math" is not a relevant argument.
