The way societies work is that the members of the society contribute and benefit in prescribed ways. Societies with lots of excess production may at times choose to allow creative works to be monetized. Societies without much surplus are extremely unlikely to do so, eg a society with not enough food for everyone to eat in the middle of a famine is extremely unlikely to feed people who only create art; those people will have to contribute in some other way.
I think it is a very modern western idea (less than a century old) that many artists can dedicate themselves solely to producing the art they want to produce. In all other times artists either had day jobs or worked on commission.
Can you list the principles across human civilizations?
What does that have to do with rivalry? This doesn't dispute the idea that AI is indeed competing with artists. You're just saying artists don't deserve to get paid.
Regardless, some artists will give up but some will simply be more careful with where and how they post their art with tools like these. AI doesn't have a right to the artist's images neither.
