Oh, there's more: Medicare, Social Security, the highway system.

The whole food/medicine regulatory system is also a big one, and it's the reason a lot of US (and European) products like baby formula are imported into China, because they can be more trusted.

My bet is the GP's going to weasel out using his "that people willingly buy" language. The flawed assumption there is the government should be conceptualized as just another company selling in the market, when the government's actual role is very different.

USPS - is self-funded, though it is operating at a loss. It also is a legal monopoly, meaning competitors for first class mail are illegal.

Medicaid - funded by the government, meaning people are not willingly paying for it

The National Park System - funded by the government, meaning people are not willingly paying for it

Every single thing you just mentioned is insolvent.
