Death to America
I guess…but…that cuts out 99.9998 percent of what most humans would call art. Including all socialist art!
Also, is a commissioned work not created solely to exist and be appreciated by the commissioner (and often the artist as well, artists like making things for others)? Is g&s only art if done by a third rate amateur musical society? Indeed, are they performing art or a product? Does a work of performance art become art when it enters the public domain?
It seems utterly absurd to call every professional artist who ever lived not an artist just because they had some kind of outside context to their work.
