You seem to not know the difference between "prediction" and "value". I have no idea why. The curve in energy is instructive on whether its optimal to sell into the spot market or sell forward. The curve is absolutely a representation of the economics of storage. It's a real price. This implied price of storage reflects the supply and demand imbalance in the market and yes, it's almost exclusively what energy firms model, NOT PRICE. Of course you laid the claim that energy houses like Vitol are just BSDs that profit on wild swings in the market. You made the claim that inventories don't matter. You then ranted for hours about the no arbitrage rule which ONLY holds under equilibrium. And it's ONLY available to holders of physical assets which is EXACTLY how firms like Vitol make their money and it's WHY they have made money for 50 years straight because surely if they were just punting on direction, they would have to get "unlucky" every now and then.
