I am challenging "pay for it with bitcoin" part here. Sure you can rephrase it as torture, sure someone pays for content access with bitcoins. But can you say that paying for actual production with Bitcoin over Tor is "the state CP today is"? If there is no evidence for this, as in at least some news article with made up statistics, then @rekord is not saying anything new.

Someone already quoted the Peter Sully case above, that's a concrete example.

Reporting about the issue also often stresses that in order to join or the cp communities you first need to provide material yourself. That makes it difficult for law enforcement, and it grows the community's content. So even if you think most cp is not 'bought', that's another concrete way how distribution encourages more production.
