Yes, I'm aware that they're an area of research in many countries, I was talking about actual projects that represent the "endgame of tyranny" as described above. The paper you've linked to talks about privacy and universal accessibility as core goals and I'm not sure whereabouts in this overview the tyranny is outlined - I'm sure you've read it and can point it out?

The issue is with accessibility, and raised by people who inherently mistrust the state, as the state can sort of cancel your participation in society if they so wish by revoking whatever authentication (digital ID) it has issued you to enable accessibility in the first place.

Now, why the state would do that, or why anyone would inherently mistrust the state, are open to discussion.
