> You already can't do any of these things without some kind of governmental issued ID which already has your birthdate on it.

Do you have to present this ID for every purchase you make or every website you visit? Will it be stored and processed by every shop you enter? If not, how is this relevant here? Currently, the personal data exists but is not accessed by anyone unless it is really required. And even then, the scope can be minimized if the user wants.

> do you really believe they don't know what you do on your personal internet connection linked to your name and payment data ?

Yes. I use Whonix on Qubes to access HN and other websites.

> but for the average HN shitposter who's already terminally online it really doesn't change much

Speak for yourself.
