That's why we should get rid of SSNs, credit card numbers, passwords, etc.

  You're missing the point. Receipts, work-related files, birth certificates, passports. There will always be information we have to safeguard. It's not feasible to switch all authentication from what-you-know (passwords) and what-you-have (certificates) to what-you-are (biometrics), which is the only way I can see us getting rid of SSNs, passwords, and credit card numbers.

    Why is it not feasible?

      Because all easily measurable biometrics are also easy to reproduce, you leak "true values" all the time as you move around the world, and once leaked, they're nigh impossible for you to change. This makes biometrics a very bad proxy for identifying you as you. And auth is all about ways to provably identify you and only you as you.
