To clarify for anyone else like me who haven’t had their coffee, this is Milton Friedman, not John Milton (I figured the lingo sounded a bit too modern).

Milton is a genius, but this particular thing won't continue for the simple reason that, if as in Denmark, you have to be tested 3 times a week to have an always current pass, then the public will notice and be strongly incentivized to care.

And that kills these kinds of programs, unless there is a very good reason.

Well, of course masks and lockdowns will be mandated if needed in the future.

If there's an outbreak of a serious contagious disease then measures deemed necessary when that happens will be implemented. It's nothing sinister, just common sense and that has been the case for centuries.
