Yes, very interesting indeed. If civil governments had heeded this advice back when the Catechism was first released, our culture would be much better off. Now, pornography is so enmeshed in the digital infrastructure than it would be extremely difficult to get it back into that Pandora’s box.
I still have never seen any rational explanation for why prostitution can be illegal, but pornography cannot. If I pay someone to have sex with me, it’s illegal. But if I pay someone to have sex with me while I video tape it so that I can upload it to the internet for profit, it’s considered “free speech” that is protected by the 1st Amendment.
Whatever lawyers convinced a judge to classify pornography as “speech” deserve a gold medal in verbal gymnastics.
