I agree that widely available pornography has probably been a net negative for society. However: 1. I'm not convinced that it is markedly worse than other harmful content which is now widely available on the internet. 2. I don't think efficacy should be the primary consideration. For instance, mass censorship is rather effective, but clearly unconscionable. I'm not sure if you can make a cure which isn't worse than the disease.
