Our generation already knows a new kind of ‘legal system’ very well. Computer games. It has a set of rules you must obey. The code is enforcing every law in the game, without a chance for the participant to break it (ofc there are cheaters and bugs). You can opt in and you can opt out as you desire.
With decentralized systems this kind of order comes to the real world and will dissolve the nation states slowly.
Bitcoin is actually a very strict system. It is a new authority with strict laws by code for anyone who opts in. There is no court, no lawyer, no judge. The code is unbreakable and you must play along. All you can do is opt out if you don’t like the rules.
While such kinds of systems would be a desaster in a world of central authorities, they are liberating a decentralized world. Efficient, trustless and virtually uncorruptable. You just need to be able to opt in and out, which will ensure every individual is participating in a system where the rules are ones someone can follow. Just like in computer games.
