is the fact that a lot of the anti-AI art arguments I've seen are basically just hardline pro-copyright takes. copyright law has far more downside than upside for anyone who isn't a multi-billion dollar corporation.
a company like Disney (this is every big media corporation, but it's a good example) has the power to identify whatever enormous brand or IP is the hot new thing and buy it outright. someday when Star Wars and Marvel stop being the biggest brands, Disney will use the tens of billions of dollars it has made off of them buying whatever the new biggest thing is. if you're an individual artist, you will never have the ability to do that (and to be clear, neither you nor Disney should have the ability to do that).
and if you're an individual artist and Disney happens to notice something you've made and decides it likes your work, it doesn't have to pay you if they don't want to. it's way easier to just file the serial numbers off your work. what are you gonna do? sue Disney? you will not win that fight.
copyright law is not your friend. it's not the answer to companies devaluing artists and trying to replace them with machines. trying to solve economic exploitation by strengthening copyright will never work.
