Anarchy = no rulers, by definition. No rulers = no rules, because there's no one to implement those rules.
You're implementing rules. You have, therefore, de facto declared yourself the law in the system. Not just that, but you're enforcing those rules through force.
That's not anarchy, that's brutal dictatorship. The rule of the strong.
EDIT: oh my me. You think anarchies have rules that are enforced by someone, rather than kept up by voluntary cooperation of the system's members. May I suggest some light reading of, say, Kant? The short version of his definition of anarchy is, if I remember correctly, law and freedom without force due to voluntary cooperation.
CMDR Peperone' is rolling in her grave, I bet.
People are attacking us and refuse to make themselves known. We're just supposed to roll over and take it? How the hell does that make sense to anyone?
And hey, we're down with Kant, but things get a little less cut and dry when you're actually out there.
