Do you think it would work? How would we achieve this?
I think it would probably work, but I think it is wrong to try and *make* it work for everybody. Once the power of the statists collapse everybody should be free to do as they please as long as they do no harm, and everybody should grant everyone else that freedom.
People will organize themselves in whatever form they want. This may be in the form of sovereign cities, villages, communities or even sovereign individuals. If you want to have a sovereign community then get together with friends to make one, that's fine, but don't tell other people they need to do so too. There probably will be a great diversity of many types of communities and organizations since humans are also quite diverse.
Just give each other freedom, that's they key (and no more lies, please).
