If LLMs like ChatGPT are allowed to produce non-copyrighted work after being trained on copyrighted work, you can effectively use them to launder copyright, which would be equivalent to abolishing it at the limit.
A much more elegant and equitable solution would be to just abolish copyright outright. It's the natural direction of a country that chooses to invest in LLMs anyways.
That's probably only worth if your state has damages above and beyond what's stolen from you; otherwise a lot of life hassle for a shitty job, which is what the deal was in the first place
