There's lots of different kinds of art, some of it more commercially viable than others. Consider 3D designers selling print models, people like myself who are interested in restoring old cars or other endeavors that are artistically rewarding and aren't just painting or sculpting. Hell, people seem to do pretty well currently as content creators on YouTube.

My point is immediately jumping to the idea everyone's going to be pumping out shitty paintings and music that no one will want is lacking in imagination.
