A millionaire driving by the artist's gallery is having an argument with his wife, who is belaboring him about his foolishness with money. He declares that it's his money and he will do what he wants with it. He see's the gallery and declares to his wife that he's going to walk into the gallery and pay a million dollars for the worst painting he can find.
You argued that the "paid a million dollars for it painting" was worth a million dollars to the buyer.
As I see it, showing his wife that he could be stupid with his money was what he found to be worth the million dollars. Not the painting itself.
He could have just as well flushed 1000 x $1000 bills down the toilet. You would then argue that having a clogged sewer is worth a million dollars?
The bottom line seems to be that the man has so much money, that a million dollars isn't of significant worth to him.
