I think the reason those restrictions exist is more important here than the rarity of the restriction. I argue this because I think the magnitude of the implications of unrestricted ingestion of public and private data is similar to the magnitude of the implications of unrestricted camera use without limit, i.e. as good a candidate for a restriction as those camera use cases currently restricted by law. The reason you cannot record what's going on in a bathroom has as much to do with the implications of the recording as it does with the implications of being observed in the first place. I don't disagree about the ensuing mess of laws, but I don't think we have a reason to believe Stable Diffusion will be spared from it.
