A solution for identity doesn't necessarily imply a lack of anonymity on the entire internet.

It sure would be nice to not have to update so many payment details after a card number gets stoken though.

Last time my card was stolen I had to update a tremendous number of services. Usually I just wait until I get some sort of notice or my account stops working somewhere but it's a pain in the butt.

Are you sure it's possible to have a solution with all requirements the article specifies yet without infringing on anonymity?

A bunch of solutions I'm thinking about suffer from one or more shortcomings.

Why wouldn't you be able to use your theoretical identity card only where you wanted? I don't show my id when I buy toilet paper, and neither would I to post on reddit.

The reason the new number is issued depends on the update procedure being non-trivial and hopefully less broad than the last time. Otherwise, they'd just let you continue using the same one. That's the most convenient solution.
