Trying to educate people to avoid all porn sounds even less likely to be successful than trying to ban things on the internet, because you cant simply teach people to not get horny in response to certain visual stimuli, and trying to make people averse to depictions of anything sexual will just lead to a repressed society that still consumes porn but is even more embarrassed to talk about it, which causes more harm than good and still doesnt solve the problem at hand. Its also a misunderstanding of the issue anyway, because the problem isnt porn as a general concept, or even the use of AI to create it, but the creation of some that depicts real people against the wishes of those people, and secondarily the possibility that it could be used to make other people believe the event actually happened due to the ability to create photorealistic images and video.

Would banning it make it go away? No, of course not, but it would make it a bit riskier to make and spread, and that would reduce the number that do it. We already have certain kinds of porn banned due to requiring abuse to create, like CSAM, and while that certainly hasnt made it disappear, its not something one encounters regularly either. An argument of “we shouldnt ban this because bans dont work on the internet” would apply equally to our ban on that material too after all.
