? for ACists: Drawbacks of an AC society?

[Taraz]

I know ACism is debated at length here on 2+2 and it often devolves into two sides talking past each other. Since often it is a non-ACer bringing up objections and an ACer rebutting, it sometimes looks like ACers believe AC-land would be a utopia. I was hoping that maybe we'd be able to flip things around a little bit.

Would any AC posters (Borodog perhaps?) mind discussing some of the drawbacks they see in an AC system? I realize that you believe that an AC society is better than any government society or else you wouldn't be AC, but surely there would be some sorts of problems. In order to get a more accurate depiction of AC, it would be useful to know the potential weaknesses of such a system that even ACers would acknowledge.
