If your warehouse is full of peaches nobody wants, you might be forced to sell them for negative dollars to take them away. It's either that, or you pay to have the waste management company dispose of them. So the price effectively goes negative from trying too hard to force something to happen.
If you turn all them peaches into high proof alcohol they take up significantly less space...
