This puts creative workers in the same boat as all other employees who do work once and don’t continue to get paid for it afterward.

And for anyone who would take this as an argument in favor of the wealthy exploiting people, no, it’s not. It’s just pointing out that it’s more typical for humans to be exploited, and the fact that there used to be legal protections to protect people who did creative work but there haven’t been protections to protect others is very interesting.
