Do you need to have the validation from others that your art exists for you to want to create it? If I read every book by only jumping to the final chapter, am I interpretating the work incorrectly or am I not interpretating it how you specifically look for it to be validated?

I keep photographs of moments as memories, eventually I'll collage them together, maybe I'll do this a few times to develop a style that I enjoy. For the argument, say that it looks horrendous but in a consistent way that I like. This collection and its output have significance to me and to others I'd share it with because of the attachment to the reflection of my identity, not because it was something I created "correctly". If AI art was generated of every moment of my life and done in the same style, it wouldn't have value not because it was made incorrectly, it wouldn't have value because it has no personal meaning to anyone.

If you view art without meaning to others being less financially valuable as an attack on all creative work, I don't think you view art much better.
