The US government maintains a revenue source to convince bondholders to keep buying its bonds, the majority (edit: large portion) of which are foreign purchasers. US revenue primarily goes to interest payments on the money/bonds/abstract liquidity it creates. This business requires demonstrating a continued willingness to raise revenues. The US’ most lucrative business has been revenue by passive tax collection, of which is receives around $1.8tr per year. There is almost zero consensus within the US for governments to be involved in nationalized industry, as the separation is seen as a core value proposition in that culture. So, for revenue of this size it is currently passive taxes that drive the ARR.
