That's not actually wealth that exists being destroyed, that's a poor measure of the wealth represented by a stockpile being revealed to be poor. The quoted market price of a unit (which is basically the marginal price of the last/next unit sold) times units held is not an accurate measure of the total value (wealth) represented by a stockpile of a marketable asset.
