I believe that a society can function in a state of anarchy only as long as all of the citizens residing in that state care for the public welfare as much as they care for their personal welfare. A society in which there is no structure cannot stand however a society with structure not upheld by a government can stand as long as all of the citizens residing inside of the society uphold it themselves. It must be a utopian society in which the golden rule is the law and no one violates it and remains in the community. For a society without structure will collapse.
