Theres "creators create because they like to create things" and "creators create things because they want to make a living off of what they create". If artists/authors/musicians/etc aren't going to be paid for what they create, they can't make a living doing it. If they can't make a living doing it, that severely limits their opportunity and time available for creating things since they could only do it as a hobby (unless we bring back royal patronage or something). Many of the best artistic works we have came from people who were able to commit 100% to the creative process. That's gonna be real hard to do if you can't pay for food and housing.
