Most economists consider the medium of exchange and the store of value as defining functions of money. But combining both functions into a single objective is problematic because a medium of exchange must circulate to be useful, while a store of value is kept (or stored) out of circulation.

It's funny how economists say that rational humans want to maximize their profits, and that maximizing profits in a society benefits everyone. But then they don't accept that individuals would want to use a money that keeps its value and isn't constantly debased.

Rational humans should like profit.. oh no, NO! Not like that!
