Everybody who has an explicit "rainy-day" fund set aside is somebody who is paying a price to try and prepare for instability / insecurity. The collective sum of all those funds in the US is probably in the billions, if not more. Futures contracts provide a more explicit way, with a stronger guarantee, of paying the price for security for specific assets / resources rather than hand-wavy guesses of how much money should be put aside for the Black Swan case. Sure, there are plenty of poor people who are so poor that they don't have any savings at all. But surely you don't think that rainy-day funds are just a theory?
