The concept that governments should be "efficient", like a business, is dangerous and denies economic reality, especially with a fiat currency. It is hard for people to wrap their heads around what it means to be the monopoly "issuer" of a currency and how that differs from their own circumstances as "users" of that currency.

When such a government runs "deficits", spending more than it collects, it is simply leaving currency in the private sector to pay for the resources and labor it demands to function. Its red ink becomes someone's monetary assets in the private sector, our aggregate savings.

These savings instruments, as long as they are denominated in the unit of account of the currency issuer, are our net money supply and they cannot be both an asset and a liability to the private sector. They require existing money to purchase, so they can never be considered "revenue" for the government. Ditto for taxes, which are a permanent reduction of bank reserves and the money supply, not "funding" for a government that neither needs nor uses revenue.
