So you're saying that places like NYC have reached natural herd immunity and can safely be opened back up? They reached an estimated R0 of 5.6 early on due to their population density. From that number, they'd have to reach > 80% infected to hit herd immunity. They got hit hard, but they're nowhere near that level. If they went back to normal all of a sudden, there'd be a lot more death.
