There is a lot of people still buying official merchandising from bands and anime etc, and subscribing to patreon and similar Mecenazgo channels (translate the spanish wiki article, because weirdly the english one does not have a version of this basic topic), even if they can just pirate the music and buy cheaper knockoffs (or just buy normal waterbottles instead). I think art will still get make through that, and because artistic vocation will still exist. Stuff where material scarcity still exists will continue to get sold of course, since making infinite anime furry porn movies in chat gpt will not feed your belly.
