Anarchy? I'd LOVE to see how long that'd work. Probably 48 hours by which time people have worked out that: no-one is producing food, you could kill people and "get away with it", no-one is going to run the powerstations, no-one take care of water supply, no hospitals. The thing with anarchy is you can't force people to enforce anarchy. People are bound to band together and then you're screwed.
