I see your point.
I'd also compare it to the early 90's when I could charger $1k for a basic website. Soon thereafter tools like MS Frontpage became available and I could only charge a fraction for the same work.
Fast forward even more to today and basically the equivalent of a SQL query can spit out a multi-page static html site inclusive of art and some other fratures in seconds.
I'd suspect in the future, people will not pay for "AI art" as a stand-alone product. It will need to be part of a bundle with something else that is more scarce to make it valuable.
