Most people are sheeps, and sheeps need to be controlled. Sounds horrible, I know, but its true. If anarchy started, club-law would prevail, law of the fittest. (zakon jačega) Not all people are good and nice. I do believe in anarchy, but I don't think people are capable of living in it peacefully. Not yet, anyway.
I must agree. It can work within a smaller communities. There will always be those which wants to be governed. Their choice.
