Just an open question since we keep getting situations like this where the industry effectively admits it is incapable and unwilling to act to stop the worst elements of the industry (child exploitation, human trafficking, forced involvement, rape etc) that it's probably best to just ban the industry together.
Notice though I said using real people, with AI slowly getting better and CGI improving, why do we need real people to make porn? Just have something animated to be realistic enough as I don't give a fuck about pixels or a drawing. Have whatever kink you want, have entire porn snuff films whatever as no REAL people are getting harmed in the making if it. The worst that can happen is stressed artists trying to meet deadlines.
This might also affect adult streamers which is just a bonus as it'll be like a re-run of Projekt Melody when she became more popular since she did more than just strip and stare blankly at the camera till donations came in. A lot of porn or porn in all but name streaming (which I include Twitch on that) get money off just simply being pretty and that's it, denying that as an easy route will probably cause a shift in a lot of media.
I wouldn't advocate a FULL ban as no matter your feeling on it generally, it is a release so going full puritan invites a backlash and probably just forces more men to deal with insufferable feminist women. But just making that release fully fictional based than support an industry that sweeps horrific practices under the rug for money is probably for the best.
If AI becomes good enough to replace actors, you wouldn't need to ban the adult film industry in the first place: people would naturally prefer ai over the real thing. For the the few that don't and would want to partake in the worst of it, they would do so ban or not. It's already illegal, better to ask for the enforcement of the current law.
I would agree the only problem is your more likely to get enforcement on current laws in civilised like the Midwest, Africa or Thailand than shitholes like California
