"someone would?". Are you the second coming of the Prophet or something? You claim you can predict something that you can't even point to an example of ever happening before, since that would be pretty important to backing up your argument. "Oh, back in the days of some king or something, some guy came along, set up a voluntary system of distributed governance, and immediately people started eating babies and raping each other".

Have a look into how the Icelanders ran precisely this kind of voluntary, distributed governance system in the middle ages, until the Catholic Church came along and used its power to violently enforce the tithe, and undid all the good of their system, which ran for 300 years with very little violence or bloodshed.

Also, have a look at the Bible. 1 Samuel 8 is a very good example to give you a hint about the fact that prior to the first king of the Jews, David, in fact, jewish society was precisely a voluntary, decentralised system of meritocratic, competitive governance. The archaeological evidence of the ancient city of Jericho, shows that this system must have existed for some 9000 years, no kings, no government, just a loose network of religious scholars who were vested with the privilege of making judgements in cases of law and prescribing remedies... These competing lawgivers kept warlords from rising up within their ranks, while they were just little upstart common criminals. It was probably this also why it was a very sad day for judaism when finally Jericho fell.
