Exactly this. This is how money came to be, "organically", in the first place. Because of modern fiat currency people tend to think that money is some sort of invention, but it doesn't take much to realize that if you're a dairy farmer then barter is completely untenable. How do you save and store enough milk to buy a car, and who has a car for sale and wants to trade it for a ton of milk anyway?
Throughout history everything from salt to spices to metals has been used as currency. There are 5 properties that make for a good currency:
- Easily divisible
- Relatively light weight / easy to store
- Difficult to counterfeit / fake
- Other people are highly willing to trade for it (high market value)
- Durable / non-perishable
You need all of the above, which is why precious metals became so common.
If fiat currency "expired" then people would just replace it with something that satisfies durable / non-perishable.
Which has rates to pay - assuming the market stands still that property is actually a liability.
Storing money in gold is probably a better example, until we find a way to cheaply create it...
