You can think of money as economic potential energy. It’s where excess economic productivity is stored until there’s a demand for it. It’s like a battery.
A battery that can hold a charge for as long as you need it is preferable to one that can’t. Even better is one that can hold it indefinitely so that it can be reused by others eventually.
Picture your money now and think at current prices how big of a “battery” do you need? If you have enough money now at current prices to last you 10 years will your money “hold its charge” that long?
If the medium you’re storing your money in is leaky then you have to expend more effort and resources just to have a stable balance. What happens when that leak is fixed?
Imagine at current levels of productivity how much more economic potential energy could be saved up just by patching that leak. What do we unlock now that we have such a money?
