I disagree -- property rights are an extension of a man's labor and domain of responsibility (no different than his body and conduct), wherin he is able to provision for his life, and any dependents. This is the domain of his "law fo the land", a king unto himself.
Proponents of the "anarchists are against the concept of property" have no foundations other than plundering the labor of others and are in service to those that seek to destroy the concept of freedom. There is no freedom without the highest degrees of personal responsibility, and that begins and ends with landownership - not rampaging gangs with ad hoc rules, which is no freedom at all, and just a big senseless diversion.
Property rights have been around as long as mankind, contrary to this reply. Every king, world over, "owned" his land, every tribe "owned" land/hunting grounds/living space. The only thing different about the USA is they overthrew the king, whereafter, sovereignty descended upon each and every landowner, only later to have ungrateful immigrants seeking "jobs" from "industrialists" return the USA into a defacto rulership by democracy out of their utter state of dependency.
