Actually those high fees are a big part of making bitcoin a store of value asset rather than a real currency. That's why people buy bitcoin and just sit on it. While if you wanted a real currency it would be better to turn to other alts..
BTC is mined in a predictable and steady manner. Fiat is inconsistent by nature so this is a moot point. Fiat is not money and should not be used for measuring anything.
So how do you suggest we measure the value of things? Using how many chicken eggs do they cost?
