IMHO, this is shortsighted. Art is of almost zero practical use. Investing a tiny fraction of society's resources in art is a sign of a society that has evolved beyond the starvation stage.

Are you saying that all art should only be commissioned by rich private interests? No investment in art by the public? You would demolish the National Mall, Statue of Liberty and other such art works?

Or do you draw the line at hoity-toity works (as decided by whom?).

IMHO, it is super important that societies develop the "refined" sides of the brain to control our atavistic instincts.
