Privacy would mean being able to fly anywhere without showing ID - which is not reality.

Please post the full street address of your home, your office, your favorite grocery store, and your top ten gas stations.

Have you traveled outside the country? Please share with everyone on HN the exact date and times, the street address where you stayed and the phone number of someone who can corroborate.

Can you think of any reason that this information shouldn't be shared publicly? Maybe post your phone number and we'll chat about it.

You probably use devices and tools that collect those data quite precisely. Banks, mobile career, cars...

We're taking about an airport... They know everything you just listed, and likely more. What an absolutely absurd argument.

In the 70's, way before any internet databases and real-time data aggregation & automated analysis, you had to show ID to buy beer.

So what? What do you suppose that proves or justifies or excuses?

The ID served a valid purpose of controlling who had access to beer, yet did not track anyone's movements or habits or compile a profile on them or associate them with others into cohorts or allow anyone to presume to make any kinds of judgements or predictions about them.

The two things are not automatically and necessarily tied. It's a disingenuous lie to act like they are and use the one to justify or excuse the other.

Indulging in a little predicting myself, let me guess what comes next, "But showing ID for beer never prevented every single underage human from somehow obtaining beer." ? Wait it was unfair for me to assume that based on some data I just collected (your comment)?

When you go through airport security, they scan your license. They're already doing everything people in this thread fear... stopping facial recognition doesn't change a thing expect let people with false identities through. It literally changes nothing... They already are keeping tabs on who you are, where you are coming from, and where you're going. Cohort analysis is already done via group ticket buys, and camera monitoring.

This literally changes nothing.

I already stole your left shoe, so, might as well just make it legal to steal right shoes.
