I think you're applying the wrong standard. If you think your work has been clearly influenced by something, you might call that out in the acknowledgements of your work, for example.
What Stable Diffusion does is effectively say "it doesn't matter how this was made" for every single artifact it creates, providing neither attribution nor acknowledgement. This happens even when it's clearly been influenced by, and in some cases is directly copying, elements or a whole of a very small set of highly influential inputs.
If a human author did that, people would probably be upset, if not outright accuse them of plagiarism.
Should every HN comment I write include a full list of everything I've ever read? What about a commercial work like a book, should that include a list of everything I've read or heard in the past 35 years of my life? That's a lot of attribution to keep track of ...
edit: I guess my question is where does derivativity end and creativity begin?
