The question isn’t whether the government can/will identify and track you. They do, in good faith or bad. This is unfortunate and attempts to allow them to decrypt or acquire additional data about citizens’ activities (like chat control) should be opposed, but identity/activity tracking is omnipresent and irreversible.
The question is whether identity credentials should be available which reduce the risk of additonal credential theft or bad-faith action (e.g. by other entities stealing non-secure-for-digital-use credentials like passports).
