Good bit of insight:
In my opinion mixing the functions of medium of exchange and store of value has caused untold amounts of needless suffering. You see 2% inflation is the middle ground. Rich people may want to save and increase their wealth but my mom just wants a job to pay rent and buy groceries, she has no grand ambitions to become super wealthy. When you mix the two functions into cash, one of the two is going to dominate the economy and with gold it was the rich, with fiat it is mostly average people because having a job is more important than maintaining purchasing power.
