There was once a German dictator whose paintings were actually very good. And they sell at auction for obscene amounts of money. Sometimes the art belies the nature of the artist. Even if I were inclined to spend a large amount on some kind of art, the artist's nature would definitely affect whether or not I bought it. If that doesn't influence another buyer, well then that's no skin off my nose. Like you said, to each his own.
