I feel we are in need of a societal shift here, just like another commenter said about the printing press. When that first came out, the pushback was from the worry that the words would be attributed to someone who never said them (reverse plaigerism). The societal adjustment to this was the universal doubt that anyone said that thing without proof.
For generative AI, when it becomes widespread, photos will be generateable for literally everyone, not just minors but every person with photos online. It will be a societal shift; images will be assumed to be AI generated, making any guilt or shame about a nude photo existing obselete.
