Attaching numbers to people is unbelievably creepy. My identity is not a number. We recoil at the idea of having assigned and tattooed numbers on our bodies and I don't feel it's okay to do it, just so you could maybe avoid misidentification.
Why did it need to go to tattooed numbers?
Also the implication that cultures and countries which have happily accepted id numbers are filled with non individualistic people is it?
You are the one somehow conflating an identity card with your actual identity as a self, which seems extremely strange and spurious.
