> ban advertising

I think advertising runs a little deeper into our identity and history than you are thinking. If you have a sign in your window describing your wares, that's advertising. If you're standing on a street corner inviting customers to enter, that's advertising. If you're doing nearly anything to make the world know that your business exists, you're advertising. I'd rather not live in a world where "ad cops" see fit to intrude and opine on such activities. Attacking PII brokers, on the other hand, would do far less collateral damage.

I'm with you on the shoes though.
