Many citizens who haven't traveled internationally don't have a passport. My American wife and most members of her family have never had occasion to get one. This is a general problem to be solved, though: occasionally videos surface of Border Patrol agents detaining people until they produce proof they're a citizen. Now, green-card and visa holders are indeed required to carry said documents with them. But citizens are not required to carry proof of their citizenship. So the statistics are actually such that a random person not having proof of legal status in the US is more likely to be here legally than not. Unfortunately, thanks to racists, it's considered politically incorrect to even require a photo ID when voting, so I don't see us solving this problem in a satisfactory way soon.
