A contact tracing system and a virus with n days of non-symptomatic incubation, and international borders. Let's think this through a bit. Of what benefit is to the traveler admitting/host country (H) to note on the "medical passport" issued by origin country (O)? Obviously, for this thing to even work on paper, countries need to exchange massive amount of information.
The fact stands [challenge it!] that the socio-political regime being rolled out in guise of defense against Covid-19 and future viral friends aligns perfectly with a specific ideological position. It really was 'Nature's gift'.
What used to be accomplished via violent revolution is being accomplished with 'scientific' efficiency and very little blood. Oh, that figurative blood in the streets of middle and lower classes? "The Virus does not discriminate!".
I'm not sure about the hand me down binary model conclusion. We're in agreement regarding the inevitability of this turn of events, but then again it was apparently clear as day thousands of years ago to "self isolating" monks.
But the clarity of the choice is stark, and like a blast of cold air invigorates one's morals and character.
Good luck!
In a way I think this will actually hamper their efforts.
After all: With the corona tracing apps, people are becoming much more aware that their data is used to trace them. A lot of people I know are talking about leaving their phones at home when they go out.
Considering the carriers have had this data forever and are probably sharing it, this awareness is a good thing for privacy.
