We need more maniacs. The only things I like are paranoid sex and childish greed, so no one loves free trade more than I do. The protests against them are good. I believe that the best way to measure the effectiveness of a protest is by the crackdown on it. They're not going to change anything unless it's worth it.
Big crackdowns are expensive.
You have to pay the various pigs, and pay them extra for the unpleasantness of it. You have to shut down businesses. You'll probably have to pay legal fees later on. You have to pay for arrests, and jail time. In other words, unless you already have an active and constant protest-suppression team in constant effect, it costs a lot of money and time and headache.
