So in those 50% antibody areas in this unethical experiment we gain the knowledge, if herd immunity is possible, I guess. Or - if it's like the flu - USA just gradually weeds out everyone that can't handle this specific disease while still rotating seasonal waves for everyone else.
You seem skeptical about herd immunity being a thing. This video discusses studies showing that immunity should be long lasting. https://www.youtube.com/watch?v=D5Z6wdu1eI0&t=270s
> The accuracy of antibody testing varies widely. Moreover, most antibody tests were done for people seeking them out, which means that those who got tested are a self-selecting group and not a random sample.
> It also appears that New Yorkers in some neighborhoods with lower infection rates were more likely to seek antibody testing.
> In some wealthy and largely white ZIP codes in Manhattan, some 30 percent of people may have gotten an antibody test. But in Corona, for instance, where the positive rate was highest, less than a quarter of people got tested.
Worth noting the limitations listed at the bottom. > The accuracy of antibody testing varies widely.

It has been said that there is some likelihood that exposure to a previous Coronavirus made some people partially resistant to Covid-19. Would that mean that there is a chance that some people test positive for Covid-19 antibodies due to a different strain of Coronavirus?
NYC's Covid data repository[1] has more data in case anybody wants to play around with it. Happy that NYC committed to Open Data[2] initiatives in previous years[3].

A positive test result shows you may have antibodies from an infection with the virus that causes COVID-19. However, there is a chance a positive result means that you have antibodies from an infection with a virus from the same family of viruses (called coronaviruses), such as the one that causes the common cold.

I have not read enough on this specific NYC testing to know for sure if they control for that somehow, or if controlling for it is even possible. Seems like it would be a factor, though.
