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.
