I heard the convincing argument that AI CSAM is bad because it means you can pass off real CSAM as "Oh maybe it's AI though". They don't want to let GenAI give cover for something bad.

So maybe the strong argument against NCII is the same - It doesn't matter how you got an image of someone, if it's non-consensual then it's wrong.

Hopefully cartoons can still be the exception since they're obviously not photographic in style. Political cartoons and satire would never be mistaken for photos.
