Btw that’s how photorealistic paintings already are.
Yes... and by making laws around the distribution or labeling of this content they can be sued. The argument that criminals don't follow the law, so there should be no law is really weak. I dont really see a problem with requiring AI porn of non consensual 3rd parties to be labeled as such at a MINIMUM. Some amount of regulation could be required and shouldn't be dismissed outright given the societal harm that could be caused.
If I knew that someone had a naked painting of me on their wall and they were masterbating to it right now, should I really be bothered by that? Am I supposed to care what is in the head of a stranger?
... and especially if some of them are actively stalking you in real life, or if you tend to get stalked in real life in general. Which roughly 100 percent of major actresses do, and a nontrivial percentage of just random women. Creepy stalkers or worse are going to be heavily overrepresented among the people who produce or consume this material... and women who have actually been stalked are going to be overrepresented among the subjects.
Oh, and by the way, if you were raised female, you're also pretty likely to have had experiences where (1) a bunch of people treated you as valuable only for your sexual potential, and acted disappointed or even angry if you did anything that reduced their ability to fantasize about how they wanted to use that potential; and (2) another bunch of people told you you were a worthless slut if you did anything sexual they didn't like. That can affect a person.
I'm actually not ready to ban things, but I am not going to delude myself that there's no downside to that.
