I agree, actually. There are interests enough in having something like this that someone will even pay artists to make the art to feed the model, and as the models improve, they'll probably need increasingly less training data, too. A human artist does not need thousands of samples to copy Picasso's or Monet's style. They need extensive training and practice to get to the point they can copy anybody's style at all (I'm completely incapable of it for all practical purposes, for instance), but once they have the training they can do a passable job of copying a style off of just a single sample. Skilled artists who have studied history and go beyond the surface of the art can even do a more-than-passable job.
e.g., there's copying Dali's color tone, realism level, and general look, and then there's understanding the why of what he is doing and being able to translate that out with some skill. You may never 100% match Dali directly, but a human doesn't necessarily need a lot of data to reach this level. And of course there will be a valid market in copying his tone, realism level, and general look even without a deeper level of semantic copying. A lot of the AI art is already this, but the person crafting the prompt and then performing a conscious selection of the result can bring their own semantics to the art in the process, it is not strictly speaking necessary to have copied them from the original artist.
This is actually part of what is going through my mind when I expect this will be solved via legislation. Well... for a given value of "solved". I expect whenever Congress gets around to this, any law they will end up passing will have HN up in arms and I expect to be armed with a torch & pitchfork myself, such is my confidence in Congress on this front. But even given that Congress is going to royally mess it up, it may yet be less messed up than the inevitable hodgepodge of conflicting precedents that will precede Congress' efforts, because while in my opinion there is no coherent legal principle that will hold the decisions together, the lawsuits will arise, the decisions will be made, and the precedents will be set. The mere inability to retain logical coherence does not stop our legal system.
