thats why i think anarchy for the most part is pure stupidity. It goes against human nature. 2 guys stand next to eachother, ones 5'4 107 pounds and ones 6'8 250, the bigger one is just going to automatically assume more dominance and naturally try to be in control, not always but to think that everyone can live together and no one is gonna try to eventually force their point of view on someone else is pure non-sense.
You clearly misunderstand even the most basic premises of anarchic theory. In a truly anarchic society, there would be no restrictions on acquiring arms or employing them in defense of oneself or one's property. A small man, such as you describe, with any intelligence, would be well-armed at all times, and by employing the great equalizer he can hopefully deter, but if necessary, neutralize the threat. Further, his neighbors, not wanting to create a precedent of aggressors going unpunished, which would threaten the stability needed for economic prosperity, would come to the man's defense.
You see, people don't need to be good-hearted for anarchy to work, at least in theory. They need only be rational and self-interested, willing to engage in mutually-beneficial economic transactions. I'm not saying that it is gospel truth, but it merits serious consideration based upon actual facts.
