You make an excellent point. If everyone liked this piece, it would be worth $150 million and not a measly $1.5 million.
Well, my husband and I have always had a rule, that we can't have any individual item in the house that costs more than the house itself. We are at the point in our lives where we are able to spend money on original art that we like, but so far we're just in four or five figures - not seven! :)
