How would that work? You have a claim to a past output that no longer exists. If the nominal value of the claim stays the same, the real value of the denomination unit must change.

People don't understand that money is a time and location bound object and pretend it is infinitely liquid and fungible when it isn't. Money is kind of like electricity. When you borrow it into existence and spend it, it travels a path through society, but it must then travel along a return path back to the source. Inflation could be thought of as a form of resistive loss, where current stays the same but voltage drops.

There's a reason why demurrage (or its ugly brother inflation) is a necessary bitter pill if you want a working money system. It forces money to travel down the return path sooner than later.
