Well the e-ID is an ID, so to the government it's tied to a person. But I know that in multiple countries it's possible to use the e-ID to only share the information necessary with the receiver in a way that the government cannot track. Typically, share only the fact that you are 18+ without sharing your name or birthday, and without the government being able to track where you shared that fact.

This is privacy-preserving and modern.
