I live my life somewhat different, that's how things are. I don't have to convince anyone that; "My way of living" is "The way of living", because it ain't, their life belongs to them. I can tell them about what I think, but that's it.

That's Cool! :)

that they must have centralized protection a central hospital or even a blockchain vote system

Centralised protection came from an earlier discussion with profitgenerator and he mentioned that. Voting comes also from him and others who love the blockchain and see the possibility to use that for voting.

The people that start that community will find that out themselves, or maybe a community start with someone lives somewhere with some ideas/rules, and people with the same ideas/rules move there.

Fair enough and that happens all over the world, like ADM in Amsterdam. The discussions I had with profitgenerator is IMHO more about the moment we would decide to trashbin central government. Then it is not about 1 community here and there, but about 8B people in the world, or 350M in the USA, or 17M in the Netherlands and I just cannot imagine that we would live in lets say 17.000 communities of 1.000 people in the Netherlands, and when we would indeed end up in something like that, I cannot imagine all those 17.000 communities will live together in peace, like the small tribes of 2.000+ year ago could not live in peace with each other. So to transform from centralised to de-centralised requires a bit more than starting small communities without an idea how to solve some of the basics required IMHO.
