The idea that the perfect society would be a society without government. Contrary to popular belief it is not synonymous with chaos.
Despite many anarchists pleas to "give it a chance" what they fail to realize is that we already have, long before civilization as we know it was created we lived in could be best described as a state of anarchy. As we can see no, however, we have clearly developed away from such a society, as is natural. The only way to prevent such a natural shift to occur would be to create rules, which would not be anarchy.
Anarchist: Shut up.
Anarchist: Anarchy! It's natural and free!
Reasonable Person: Shut up.
