However, if we want the cryptocurrency to be a means of payment in society and each state even simply allows its circulation on its territory, and even more so, takes it under its protection, including judicial, we will have to accept some additional rules of this state and it's nothing you can do. Cryptocurrency will be able to continue to develop further only after the states legalize it.
In a theoretical pure crypto world where everyone controls their own keys and there are no third parties then there is no need for any more rules. And there is no way of enforcing any rules either.
If someone steals from you then there are existing rules to nail them.
I absolutely believe that any third party who takes control of your keys should be regulated until their dick falls off. We have nearly ten years of utter incompetence, dishonesty and failure to prove that internet strangers are shit and need to kept on the tightest leash imaginable.
