Without art and all the great artists we have had, our world would be much different today. Everything in life plays a role, every job in society plays a role and if it were taken out, society would crumble.
The reason we have art is not (entirley) related to money, markets or IP.
Artists would continue to create for free. They have no choice in the matter. Ask any artist and they will explain.
Your forgetting the part about having to work a separate 40 hour a week job
and what that does to ones time , energy, and output.
