With that in mind, isn’t the legal burden on the model output rather than the model weights and training? An artist has the capability to reproduce something copyrighted, but that’s generally only a problem if they try to sell that reproduction. In that regard, Midjourney probably is in violation of copyright because they profited from making a close reproduction of an existing work. But a solo person running Stable Diffusion locally probably isn’t, even if they made the same output.
