Can pictures you keep of your own children ever lead to someone else concluding they are child porn?
I see the question you're edging towards is something like:
If no harm was done to anyone, can it ever be wrong?
Possibly in the eye of the beholder.
If you like to draw people in weird positions, and they are forced upon no one, they should be part of freedom of expression.
The "generated" part I feel could have some issues: What is the source material of the model the AI required to generate the not existing person? It could be as wrong as stealing texts from others to generate "your" book. Still wrong if direct plagiarism...
