Govern (control) mente(mind) So not Quite the meaning you infer. Though in concept sure its Managerial structure. But a centralized one, not decentralized.
Who whould make the rules in an Anarchist Society? They whould be decided upon by consensus of all who takes part and enters into that society. I.E some core rules could be decided upon by the once that first start it. Then all who enter choose to either agree or take an interest in looking at the rules and talk it over with others in that society to see if they are good enough to server the people and freedom.

Though ofc if the mentality is too lazy of most of the once in an anarchist society, it can happen that a group takes over and manage to change it, but at that moment its no longer an anarchist society. So you could in a sense then say that; you cant prevent stupidity or ignorance.

So it does depend on the members having a sertain degree of integrity and responsability. Genuine people you could say. This is true in however we end up doing stuff if we are to come into any form of freedom.

SO if you want to define every individual in the society to be "the government" then thats up to you. But the concept is decentralized.

While how USA started may contain some aspects of what could also be the start of an anarchist society, how it was started was not decentralized and anarchist. It was a centralized hierarchy at the very beginning from what I understand. So its not quite reinventing the wheel.

Oh, and Liberstad and Liberland isnt Luke and Jeff's projects. Although Jeff is very much involved in Liberland if im not mistaken. They did however visit that village that got rid of theyre government. And documented stuff from that place that is yet to be released.
