What would change is the government would need to greatly increase their debt. In 2025 the government got about $5.23 trillion in tax revenue and spent about $7 trillion. So most of the government spending is financed by taxes. Remove that and the rate of debt quadruples (and by extension inflation).
Fact is US is able to run up 39 trillion and counting in debt because it prints the god damn monopoly money. No one would offer a loan to someone with that financial history. Shit really went off the rails after Bretton-Woods, huh?
