> Countries don’t really want unique IDs per person

Given the number is countries that already have those and those that attempt it every few years... I'd say it's not correct.

For spies, you just issue multiple identities - the origin country shouldn't have any issues with that part. It already happened for witness protection level stuff.

For voting... yeah, that's a citation needed. Politicians mostly worry about foreigners coming to vote.
