Don’t expect currency to be a long-term store of value. If you want to hoard dollars, do it in an interest bearing asset or in precious metals.
Currency only needs to be a stable short-term store of value to facilitate transactions.
Price is information. Inflation/deflation corrupts the information.
What is the politically corect time frame? Who made the state, and traders the arbiters of when, how long, how fast trades should be made? Is it any wonder, long term projects can not be economically undertaken when you are unable to plan on stable values? From the late 1700 until the beginnings of the Federal Reserve we had a stable US dollar, and with primitive finance, bad to no information, no to very poor infrastructure, we built the wealthiest nation in the world, literally from nothing. We built cities to rival anyone. From nothing. Now? We can't pour concrete. Yeah, this is working out good.
