the cameras that track your every movement inside a supermarket (plus the software that labels your image with a unique identifier) have you pinned down pretty well already, no need for nametags.

Don’t forget the Bluetooth beacon trackers.

Only in some places.

more places than you would expect though.

Being gratuitously anti-social in a pub or supermarket already has consequences, name tags or not (you'll get kicked out). It doesn't matter if people know your name or not, they'll recognize your face, and you might not be welcome back.

Being gratuitously anti-social online might also have consequences (your account gets banned), but if creating another anonymous account is free and easy, then the consequences are trivially ignored.

You could make a distinction between anonymity and ease-of-creating-new-accounts, but usually the two are tied together.

No, but I also don't wear a mask that covers my face and I don't use a voice changer to scramble my speech.

In meatspace, people use different modes of identification than just a name, so names aren't as important to figuring out who's who.

> You wear a name tag to the pub, or supermarket?

Yes, but I don't realize it.

I don’t, yet I am still not anonymous. If someone at the supermarket asked me my name I would tell them.

You don’t keep your phone with you?

Or always pay cash?

That doesn’t help if every other phone in the vicinity of the business gets a ping from your phone.
