The effusion of arms matters little. Most people need and rely on the power structure of some type of governing body to regulate behavior and keep things orderly. They WANT to be controlled and protected. Look what has happened to the USA. It went from a Constitutional Republic to a Banana Republic with a ridiculous level of governance in only a few generations.

If 1000 like minded individuals could form a peaceful society on a desert island with an abundance of resources, I guarantee you that they would be invaded and would either have to kill to defend themselves or be killed and assimilated into the new population.
