The average person doesn't care at all about the idea behind a currency or even if it's a good currency fundamentally they just want to be able to trade it for want they want.
Walk into a store, grab an item, walk to the counter hand/swipe/tap/scan currency, BEEP, done.
Utility is what matters most of all to the average person.
People do care about currency stability though because if you walk into a store and buy one loaf of bread today for one unit of said currency and then you walk into the store and buy another loaf of bread tomorrow and it costs 10 units of the currency. People get annoyed. Now, if they walk into the store and buy a loaf of bread and it's one unit of currency today and then they walk into the store 10 years later and it's 10 units of currency, they might be willing to forgive that.
