The market for creative works breaks down as follows. You have pay-in-advance arrangements such as patronage, commissioning, and so on. Those have been around forever. And then you have pay-if-you-want-it arrangements which only make economic sense because we have laws that grant monopolies to the creators of the work over the market for copies of that work.
The first arrangement is very clearly a labor arrangement; but the second one is a deliberate attempt to force artists to act like capitalists. More importantly, because art is now acting like capital, it provides an obvious economic instinct to centralize[0]. So you get industrialized artistic production under the banner of publishing companies, whose business model is to buy out the copyright to new creative works and then exploit them.
What AI art does is transfer money from the labor side of art to the capital side of art. The MAFIAA[1] wants AI art to exist because it means they can stop paying artists but still make royalties off selling licenses to the AI companies. This increases their profit margins. Meanwhile, the journalists can't sell you old news; they need to spend lots of time and money gathering it every day. That business model only works in a world where writers are scarce, not just the writing itself being artificially scarce.
[0] We can see this with cryptocurrency, which is laughably centralized despite being a deliberate attempt to decentralize money.
