It doesn't, as this is issue has not been decided by courts or laws yet, and opinion seems to be evenly divided. So this is circular logic.

You mentioned MP3 (compressed versions) as comparable in functionality, and my argument is about how they are not similar in functionality, so the conclusion doesn't follow as they are not comparable in that analysis. Compression not absolving copyright infringement doesn't lead to the same thing being concluded for diffusion models. As you asserted that, you need to show show compression and diffusion follow the same functionality for that comparison to work. That's like if I say that it isn't illegal that I can look at a painting and then go home and have vivid images of that painting therefore diffusion models are not doing any infringement, that would be fallacious and wrong, functionality doesn't follow, the same for MP3 example.
