CSAM laws in many jurisdictions include computer generated or hand crafted media that do not pre-require CSA at all. The idea is that deviance leads to CSA, and by cracking down on CSAM, we are preventing CSA.
This is such a slippery slope. It amounts to thought police. You did not actually cause any harm, but thought of doing something. Where do we stop ? If I fantasize about my pretty coworker without her consent, am I a rapist now? What if I make a sketch of her naked? Is that a crime? What if I ask AI to remove her clothes from a real picture? Even if I just immediately delete it?? I guess that there’s different levels to each “offense”, and at one level it does become criminal, but it’s hard to unequivocally decide where.
