The PASS card features your name and photo, it's an ID by any other name.
You must have a very warped perspective of social reality if you think it should be acceptable to force every adult to show their papers before they can do anything in modern society - and all that just so you can avoid your parenting duties. And I say that as a parent.
I'm not worried about my parenting duties. I am worried about the inequality created for the kids if I am strict about rules, but other parents are not. That's why it is in my interest if other (lazier) parents are forced to comply.
And yes, the PASS card has name and photo. But no adress, no social security number or secret ID or equivalent. If your PASS card leaks, nobody can create a bank account in your name. If your passport leaks, they can. That's the difference in privacy, seen in action.
Some people just want government to parent them.
