The problem in the US is that the government doesn't necessarily have all of your details. Most people's ID is a driver's license, but you're not mandated to have one of those. The federal government doesn't control those databases (hi, REAL ID), and few people actually have passports. Your citizenship documents are just a birth certificate that is an image on file with a particular state's health department. A centralized identification system on that scale in the US would take generations to get up and running
