I'm not talking about taking millions of peoples art, and then feeding them to the grinder. I'm talking about one artist, whose art was taken to train a model to replace him.   
Also, it takes time to get good at art. To spend months of your time to study one artist is a show of respect and honor towards that artist. Does the Ai do that same thing out of respect? no, it did it because the user wanted a cool picture.

In that scenario what it comes down to is what you think the value is in art. For some people it may just be a cool picture to look at, and in that case art is just like any other commodity, the consumer will buy the coolest picture at the lowest price and who made it is irrelevant. For other people the value is deeper than that, and actually comes out of a respect for the artist and the effort they put in, and for that person an ai generated art will have no value and will never be able to replace an actual artist.
