You can leave the country without a problem, without a passport or any identification. You just cannot enter another country without it.
This is exactly what I said, as it is, and as it should be.

But by then they've left their own country, which now won't let them back in, for the same reason, and they end up living in an airport for the rest of their lives.
In practice, that's not how it goes. Last time I tried to drive into Canada, my group was turned away by US customs to prevent that kind of deadlock. In the movie The Terminal, his legal standing to enter the USA was destroyed during the flight. In the incident that movie was based on, the man lived in that French airport because of a similar change of status
en route. Countries are polite enough to each other and responsible enough to the public in general to watch out for each others' citizens.
