No it doesn’t. If I set a price on my time in the game, i can with coin cause it holds some kind of buying power, footfall is a constant generation of currency and tax a constant take away (some times portal costs as well), so you can gauge how long it will take for that amount of currency to generate. So time has a direct relation to how much coin it is.
By generating an option to generate currency from thin air you increase inflation (in IRL terms lower the rate of interest so banks can loan money for cheaper and loan more money to people thereby generating more money that is circulated) if you want to stop inflation you want to reduce the currency that is in circulation (higher interest rates etc) with allowing players to hunt for currency straight up you will only ever increase the currency in circulation an thereby driving up the inflation.
(I know the IRL is simplified )
