Just because the ai produces a model with Billie eilishes face and a naked body does not mean you've seen her nude for real.
Its the exact same as drawing a naked lady and then drawing Billie eilish's face on it.
If that really gets you off and really violates her autonomy in some way I'd be interested to hear how. Its not currently illegal to draw real people in fictional scenarios is it?
While thats all interesting to read, you are adding in so many additional variables, we aren't talking about whether the game is too big or not anymore, we are talking about how you are slowly being buried in debt and at the same rate running out of things that make you happy.
