I understand the mathematics. The problem is that there is a practical asymmetry of information. Large future traders can invest a lot of resources into getting a much better prediction of future prices, while individual farmers cannot. In such scenarios, it is inevitable that farmers will be exploited by future traders into making bad deals.
