It won't happen, it's just Utopian ideas, humans will just not go for it, and if you want proof just read all the comments , everyone has his own idea about how things should be and in the end some people will ally with others and start controlling everything and we are exactly back where we started. The ideas are great but they are not realistic. Humans are just like that, in fact I can bet you if things are too good somebody isn't going to like it and just start a movement to end decentralization just because he's against it.
Remember English isn't my native language so I might have mistakes that might make my meaning not so clear.
