The relationship between futures traders and farmers is pretty much identical to that between any kind of insurance company and its customers - it's a risk arbitrage transaction where the client (farmers in this case) are sacrificing profit in expectation for a flatter outcome curve which in a properly priced market yields higher utility in expectation, since utility as a function of profit is concave for an individual farmer and much closer to linear for a well-capitalized market maker.
