Anarchy is just a concept of society without an official government. The danger to this is the "power vacuum" concept. The concept is rather simple, if you were to take away power from A, B or C, other groups and organizations (X, Y or Z) would arise to claim that same power over others at some point in time. Human power is simply a source of energy and energy is always transferred from one node to another node. There is a reason our Founding Fathers warned us we would have to feed the tree of liberty with blood from time to time unless we wish to perish.
