In a sense it is if it's tied to value, you can print trillions of empty dollars but the ratio will be the same if there will be no growth behind it, now instead of 1$ you will pay 10$ for something, so maybe amount is not fixed but representation or ratio or how you want to call it seems to be.
People conflate money and value / wealth. We can individually create things of value: food, art, services, inventions, shelter. There is no practical upper bound. Money is a medium of exchange from one to another. Having more money in the system means it’s easier to get bandwidth to transfer that data between interested parties. Without it, you are inefficiently bartering to exchange value.
Value existed long before money, and its potential for creation is not dependent on it.
