The natural human order is anarchistic, as the author of this article points out quite eloquently. Government is a perversion of natural community, which is a consensual ad-hoc kind of thing. It is increasingly taking over the family as well, replacing father and mother with courts and CPS "professionals".
Government has no limits. That is the problem.
I might be for anarchy if I though people would follow the Golden Rule. The problem is they don't.
Sure, the "natural order" is to not have government...or computers, or electricity, or cars, or modern medicine, or indoor pluming, or...
Anarchism only works in very small, mostly isolated groups. The larger the society, the more easily people can abuse/rob/kill others and get away with it.
