The kind of art you're talking about is "high art" and it's a luxury item. The majority of artists don't produce that type of art, and will instead lose out in this scenario.
A Ferrari is a luxury item. The exhibition was free but you could pay to stay the night. The guy also designs slides and the tone of his exhibition style is not "high art".
Ultimately you are talking about art as a product and that means you think all art is captured by Warhol's system of art. Which is what all digital artists overreacting to this also think. It's not the totality of what art is. I like DALL-E. Good work, but now what else is there beyond digital art? Or by pushing digital art to some more extreme outcome?
Technical artists are far different from performance or exhibitionist artists. They aren't even in the same realm.
Yeah, art is vast. It includes me saying "Kerflaffle!!" while I ride a unicycle and fart out a candle in a dimly lit room. But that doesn't usually pay bills and most artists don't do this type of art. It serves a different audience/consumer. It has a different market cap. Let's not confuse oranges and grapefruit.
