I agree that hedging can be considered a speculative act, but so can not hedging. It's a perfectly symmetrical situation, and free if one ignores trading costs, which are almost negligible to professionals.
On the other matter, though, I have to stress that I am NOT describing a theory of how forward prices are determined. That is how they are actually set in practice, everyday, at all times, in the trading desks and commodity exchanges. If you don't believe me, just ask any finance professor in your university or commodity trader. The best way to grasp this intuitively is to consider that any other situation creates arbitrage opportunities that cannot last more than a few seconds. Many trading houses have program trading software set up to take advantage of any tiny misalignment that arises. These programs buy and sell positions instantly to capture the discrepancy, with zero risk, bridging the gap and eliminating it.
