Don't forget the porn industry are tech innovators/trend setters too.
One of the reasons VHS won-out over betamax was because porn producers/actors preferred to use VHS set ups/tapes.
Now with all the VR stuff and different sorts of feedback sensors...well, I'd say look at Ghost in the Shell connectivity and Ready Player One's haptics are not that far off.
As well, Prohibition showed how badly this sort of thing usually goes, and how it usually only empowers organized crime and people who are anti-porn crusaders, while turning even more people into needless victims and/or criminals in the same act(s) that are legal currently and have been for a long time.
Porn needs some cleaning up for health and safety reasons, and more ways to ensure the safety of performers/actors. Also more safeguards against trafficking and scam/abuse schemes.
Modern sex ed classes in high schools need to handle things in basically a 'ask your parents' methodology when it comes to porn; parents really are the one's who should handle education about this sort of stuff, not schools or bureaucrats.
Banning porn makes some people feel righteous, but most of them will admit they cannot do it without violating the 1st Amendment and likely enabling a Prohibition 2.0 that is even less successful and more damaging.
