Don't entirely disagree with what you're saying - I believe Dall-E 6 or whatever will get to that level of sophistication. One more thing though - I felt the painting is worth more because the artist toiled for it. It's like a "lofi 10 hour soundtrack" on youtube vs. an album from an acclaimed artist. I listen to each song 100 times over from the latter meanwhile the lofi video just plays in the background. Knowing someone toiled over it and put their heart and soul into the art gives it the value, for me.
