Exactly this. As late as the 2001 I could cross into the US from Canada with as little as my birth certificate, which I often did. That was just a cotton blended paper with tattered edges with some writing, and the crest of my province printed on it. There wasn’t even a photo on it! It was closer to writing, ‘I’m daniel plz let me in’ on a napkin, than it is to my passport of today with its photo, barcode, and RFID chip that they can cross reference their data base with.
