It's funny how you assume that structured can only happen with violence. You're right, an advanced anarchist society would be a real democracy (not a representative democracy like we have today). It would in fact be way more structured than societies today. If a small group of people can't simply enforce rules on all the others, the bodies that make decisions for the group will have to do a lot more work to make sure they are including everyone in the conversation in order to avoid conflict. It would involve a lot more conversation, deliberation and balancing than our current societies.

The vast majority of humans are actually nice, altruistic and not selfish if you treat them with respect. And hence anarchism would not resolve in everyone killing each other.
