We are social animals. Art is storytelling. It has many utilities, but it is primarily education and entertainment.
A modern version of the cave painting is to distill complex and uncomfortable truths about the world for those who wish to thrive in a society built on lies.
If you want to go dig shiny rocks from the mountain at great personal risk to your mental and physical health for no benefit to society you are probably sick. If it heals you, that's its utility.
But if you find you're good at it and you want to use this skill for its intended purpose, you aught to be getting paid for it.
*Your mileage may vary. Just my take.
