Some countries, like Australia, require you to show the airline a valid visa before you fly. If you land without one, the airline is responsible for the cost to repatriate you. Obviously to get a visa, you’d need a valid passport.
I don’t know about TSA (I’ve never not used my passport as ID when traveling internationally).
But the airlines will validate your documents before giving you a boarding pass. You have to either scan it into the app or show it to an agent at check-in.
I haven’t traveled out of the US in quite a while but I don’t think you have to show TSA a passport but you do need identification to get through

Now I’m tempted to start an online service to issue visas to all destinations for World Passports owners…
“But I got a visa! See? It’s the $500 visa gift card that I used to buy this passport”
Yes, but heavens forbid getting a bank account.
