> "What people would pay for it" is a controversial quantity

Yep. A friend thinks we should have a "You bought it!" law for insurance companies that assess the value of your belongs to calculate a premium. Basically once they give you their assessment, you have to right to say, "You bought it!" and they have to take it off your hands at that price. Not that such a law could work in the real world, but it is pretty clever. I bet a lot of people wish they could use such a law for property tax assessments.
