The thing is you don't leave on a passport, period. There is no outgoing border control in the US. The *AIRLINE* wants to see a passport because they want to make sure you'll be accepted at your destination, not because of any US rules.
If you leave the US by land all you'll encounter is the Canadian or Mexican border checkpoint.
