Hmm what do you mean by centralisation? I'm happy there are roads and lights. Schools? It depends what school we are talking about here. People built those roads, schools, and lights. A belief in a system that is unjustified and not real doesn't make those roads get built. People who want something will make it happen. Giving someone else more authority over almost all aspects of your life will only stifle progress. The people who built the roads make having roads possible. They don't need permits, "laws", and taxes to work. I don't think anyone truly trusts a politician to keep their word and deliver on their promises. Or trust them not take bribes to certain special interest groups. When you say we need centralisation in order to protect certain things understand that this very centralisation or control you give to a government is more corrupt then any privatisation could be. This false belief that governments actually provide the control they claim to bring to any industry or anything needs to be brought to light. They are a big gang, they don't provide protection they are the very thing we need to be protected against. People can still learn and work together and have leaders in certain aspects and projects of their lives without giving them authority they themselves don't have.
My liberty is non-violent unless violence is brought to me. Anarchy is not as chaotic as the current system we have. It's self governance, personal responsibility and cooperation. It's nobody taking a cut of your money unless you believe they provide a valuable service to you. It's actual freedom. Centralisation has been tried for a long time it has some major flaws and it's time for something new.
