Not really the same is it. You are confusing a stock and a flow. Currency is exchanged for something material you have to give up.

Government may indeed issue more currency, and does do so every day, but it is in exchange for something the private sector has that it wants for the public service. That isn’t a problem as tax is a percentage and operates as a geometric series - meaning that whatever government issues it gets back exactly the same - unless somebody along the way saves it.

There has to be something available to buy in a currency for it to be issued. As we see in the game.
