Food as Currency

There are many options for alternative currencies used in small projects around the world. The key ones are: time, precious metals, energy and food. Today I spotted this project using food as currency. Best of all, we can and we should have all of these currencies at the same time. Let there be a truly free market without monopoly. Let the fiat paper money compete with time, precious metals, energy and food money. I certainly would have a little bit of each currency. Food money makes food storage convenient and is best suited for true emergencies. You can't eat gold, but the food money is backed by real food.
