Imagine if a regulatory body decided to limit the number of durians purchased by each individual in order to lower the price of durians so that everyone would have the chance to taste the King of Fruits. What would happen?

If this campaign was successful to the point that prices fell to close to or below production costs, durian planters and sellers would rather walk away from their plantations and let the fruits rot on trees than to harvest the fruits, transport them to towns and sell them at a lost. Economics 101 tell us that when supply reduces, price increases.
