Authority only exists if you believe in it. If you don't believe in it, the world is run by very powerful bullies, and your job is to make them disappear. That's the core of anarchism, I suspect—the belief that no one's more entitled to power than anyone else. I think many anarchists would also agree that anarchy is the ultimate form of egalitarianism.
