I know you're being funny, but for most of history real (as opposed to nominal) rates of return on cash have been negative. Sure, you wouldn't be paying the bank interest, but you'd be paying for storage, security if you have enough, losses on rodents eating your cash, etc. Positive rates of return are actually quite a new phenomenon.
