It is too idealistic to say that art is an independent, breathing body in and of itself. No matter what, when a consumer purchases the art, it funds the artists’ empire. It fuels the artist's capital to continue to stay in positions of power and exploit those below them. It funds the legal battles against victims to attempt to silence them and destroy their court cases.
Art isn’t even spiritually separate from the artist because it was the artists’ idea that gave life to the art in the first place. Without the unique stage presence of Michael Jackson, his songs would not have been half as popular. But even if the art was separate in spirit, the necessary and direct consequence of a consumer funding a piece of art is that the artist earns money. When that artist is a sexual assaulter, that is a very bad thing.
