given the science here, and the mathematical likelihood of most people getting substantively sick, this stupid fiasco is already exceedingly difficult to justify - the vast majority of people are no doubt in a state of shock, and aren't thinking clearly. when they wake up...
if you can present an easy antibody test to demonstrate immunity and prove you're of no threat to the general public, it makes it that much harder to justify these draconian measures.
and, people pushing back against it should be denounced as anti-science luddites.
