Hedging everything in life

How peaceful the life would be if I could hedge everything I use for a long period of time (say 30 years) . If I could hedge things like specific quantities of milk, spinach, carrots, chicken and so on, it would make retirement planning so much easier. I could pay for all these costs much earlier. This kind of insurance would provide me great sense of economic security. Famines, wars, hurricanes would not affect the cost of running my life. In the long run, businesses would have incentive to reduce prices of products, to make these derivatives worthless.

Departmental stores can sell derivatives for food products like bags of rice and wheat. Hospitals can sell promises of future health care. Airlines could sell derivatives of flight tickets for direct routes. Starbucks could sell derivatives promising guaranteed price of lattes and so on.

Imagine a day when you go to Starbucks and the barista asks you "how much does your tall latte cost?"
