I don't have a fancy liberal arts education so perhaps I'm misunderstanding the finer points of anarchism. As I understand it, the concept involves rejecting authority and hierarchy and neither of these is true of the scene.

Certainly things are not organised as rigidly as a government or traditional business, but neither does the scene resemble a collectivist commune. There are authority figures and hierarchies everywhere. The fact that there are quality standards for releases, that all groups (of any note) adhere to, and which are actively enforced throughout the community, should be indicative of that.

Let me spell this out for you a little further: everything from groups, to sites to individuals have their place in a pecking order. Each group for example is its own mini fiefdom; usually ran by a single leader or a council of elders. They decide what releases the group will target, what site affils to chase, what resources are required and so on. You march to their tune or leave. Initial (and often continued) membership is based on performance: if you impress with your chops, you're in. Drop the ball too many times and you're out. Always the objective is to be the best.
