It is not the federal government's place to force the funding of art via taxation. It's a crime, really. Government has absolutely no justifiable role in the arts. The value of art is irrelevant to this issue - the role of government is to protect against infringements that threaten life, liberty, or property. Bankrolling artists that wouldn't be able to convince free people in a free market to fund their projects voluntarily is literally the exact opposite of the government's role.
