Ok, and? Presenting your ID at a number of IRL estamblishments also heavily reduces anonymity

The difference is that IRL establishments don't sell off that data to anyone else, nor do they have the ability to collate that data with data from other establishments to make a profile of you.

(at least not yet)

But to get that ID from the bottleo, you need to hold them at gunpoint.

To get it from Discord you need to sneeze.

The internet has scale and availability, that physical locations do not.
