I'm not personally a fan of anarchism but that seems like a weak argument. Many people of that persuasion also support significantly down-scaled local and self-sufficient communities or pastoral lifestyles, I very much doubt that Bakunin had modern Montreal in mind as a sort of model society for anarchism.

For a different take, do the Amish have a police force or are they frequently policed from the outside? Many people who advocate anarchism do so in the context of communities in which widespread looting makes little sense.
