Yes. If you steal the ID card or passport of a person who looks like you, you can do most things in life in their name. Take out a loan, travel the world, get married, etc. The major benefits compared to SSN authentication still are: * It's a physical object, you have to be physically present to steal each one instead of getting a hundred million at a time. * Most people would quickly notice that their card is gone, report it, and get it revoked. You only have between a few hours to a week to use it, not the next 50 years.
