Good piece but I'd argue that property is violence, since it is only yours as long as you can defend it. Most people get along and cooperate, and a cup of coffee is hardly worth the risk for a criminal, but if you were holding a kilo of pure gold instead of coffee someone would conk you over the head rather quickly. The more tempting the property the more force or threat of force required to defend it. Not all property is acquired by violence but nearly all of it is retained by violence.
