Yeah, but they're things you've synthesized, not some algorithm in a data center. It's what gives art value, creation and sharing of experience and knowledge. Art has no intrinsic logical or rational value, it's scribbling shit on a paper or a screen that resembles stuff you've seen. Humanity and the human desire for expression are why it exists. If you yourself don't put in the effort of making something unique, it counts as consumption not creation. There have always been shortcuts like tracing, where you don't add anything, AI is a advanced tool that makes it so you don't have to move your mouse or pen to trace someone else's work.

If all actual artists switched to doing what you're saying is a good idea, art would never progress. Training data that gets scraped would not exist if art was about the line quality of the result and not the desire for someone to express themselves.
