All murders are non consensual how do you know if mudes are non consensual? Would it also be illegal to draw a nude picture of someone?

I responded with a little more detail to a sibling content, but if laws for banning CSAM and meth exist due to the negative externalities of possessing them - that's where I think this is different. If we see laws come about for regulating AI private-use content production, I suspect we'll see some unique court cases about it, premised around free speech / lack of harm.

I don't think the analogy to generative models holds. The possession and consumption of meth and CSAM _drive_ production of meth and CSAM; it's a supply and demand market. So simply possessing it harms others as well.

A generative model is different. You can produce as much content with it as you want, hallucinated out of thin air. The production of said content doesn't have externalities, other than electricity usage, if the content isn't distributed.
