ideally? It means that AI companies have to throw away their entire training model, pay for a license that they may not be able to afford, and go out of business as a result, at which point everyone snaps out of the cult of AI and realizes it's as overhyped as block chain and pretends it never happened. Pardon me while I find a flea to play the world's tiniest violin. More realistically, open models will be restricted to FOSS works and the public domain, while commercial models pay for licenses from copyright holders.
Like, what, you think I haven't thought through this exact issue before and reached the exact conclusion your leading questions are so transparently pushing that open models will be restricted to public works only while commercial models can obtain a license? Yeah, duh. And you know what? I. Don't. Care. Commercial models can be (somewhat) more easily regulated, and even in the absolute worst case, at least creators will have a mechanism to opt out of the artist crushing machine.
