This is how we know AI should be a collectivist project, one that isn't owned by large corporations but is funded by taxes and developed in academies, and all IP derived from it falls into the public domain.
Besides which a lot of artists mind a lot less when their material is borrowed by a non-profit, or to serve a public works project. (There are exceptions. Disney is notoriously litigious about murals in nurseries.)
PS: Development of a robust public domain is the only reason that intellectual property should exist at all. Also it's not property so much as a licensed temporary monopoly.
PSS: History has already shown us that people will invent stuff and do fabulous art simply by being allowed to live in a state other than desperation. Public welfare programs beget art booms. The most recent example of this was during the COVID-19 lockdown which came with extended unemployment and stimulus checks, resulting in the Great Resignation in which a lot of people turned their hobbies into something lucrative.
