> Coincidentally, these same people think the most “artistic” process is the most intentional one.

While people do think like this, it misses the point.

Yes, all forms of art is FULL of randomness and people copying each other. The thing that makes it special is that it took people going out and living and having experiences to create it. They have to actively absorb prior art, learn about it, analyze it, generally be influenced by it. You have to seek out paints, clay, musical instruments, etc etc and at least somewhat learn how to use them. It's not about being difficult to do (although it's certainly impressive but not part of the emotional takeaway), but everyone's process is different and their experiences go into what they create. When I see a photograph of a tree, I think: "Someone went to where that tree is!" and that's part of the feeling and excitement of a really artful photo.

Now, someone who has only ever heard the term "free jazz" can sit in their parents' basement and type out "make me a free jazz song" and shit out the result onto the internet. It's really not the same thing at all.
