Everyone has their own ID, no need to carry around a whole paper notebook called a passport, which can hardly fit in a pocket normally. Also, do not carry a notebook to the club, where you will definitely lose it easily.
Everything goes through the ID: checking in for a plane, going to a bar, banking, medical care, etc. It's incredibly convenient. By the way, if you lose, then if you have rights, you can use them, they are equivalent.
Therefore, upon arrival in the States, run ID so as not to wander around with a passport. My friend once lost his, and you know what? It is incredibly difficult to restore it in the States, you have to find a person who will confirm that you are you. What if you came alone?
