The heart of Ken's article can be expressed in two quotes he uses from Makia Freeman.

When you put them under the microscope, government and political authority are not legitimate; they are force. The terms limited government and government by consent are oxymorons, because there are no good examples in the real world of a government that stays limited forever, and a government never really has the consent of all its citizens, most of whom are simply born into an existing system of coercion by coincidence of birth (and taught through indoctrination to never question it). —Makia Freeman
The stateless society trusts the inherent tendency among humans (and Nature) to cooperate. Yes, there is competition in life, but the greater part is cooperation, symbiosis, trust and harmony. It is possible to find win/win solutions that don’t require the need for an outside authority, and to take that model and apply it to a whole society. To continue to believe in authority is to create a game where you may win or you may lose; it’s creating a throne or seat of power which “bad guys” can overtake. It’s well nigh time for humanity to grapple with the question of anarchy vs minarchy, to move beyond the fears which are holding us back from creating a more free society. —Makia Freeman
