Alan, with respect, I think you're a libertarian, not an anarchist, at heart.

Anarchists oppose government because they think chaos is somehow desireable. Libertarians oppose government because it doesn't work very well, due to the inevitable corruption of power, and because people ought to be able to achieve an orderly society simply by everyone acting intelligently - quite selfishly, but in their own long term self-interest.

I think the loud, amplified, buskers are the anarchists. They're at risk of creating a noise war that will drive away the audience, or get all buskers banned, or both. Acting contrary to their own long term self interest.

Or so it seems to me, from the outside.
