One could argue that your Passport # is a national ID #
obligatory "papers please"
Except only people who go out of their way to get a passport get a passport number. Which means that the vast bulk of Americans don't have one.
That a valid counter argument, sure.
The real irony is that in the state of Texas, you can get a Texas ID card which is basically a Texas DL card, sans the ability to drive. But if you look at their registration process, you're required to provide ......*drum roll*....and SSN number!

So basically, the SSN that was explicitly stated to
not be a national ID, is in fact a defacto national ID.
