The NBA quarantine works because it's for a multi-billion dollar industry and aimed to protect fewer than 500 players. Over a million people are in nursing homes, and more than another million work in them. I am not sure why you think it's more realistic to lock down three million people totally than have most people take moderate precautions. Remember, this is in a proposed scenario in which the average grocery shopper will have a high likelihood of being infected, without masks or any social distancing measures being taken. The White House tried the "frequent rapid testing" strategy, and that didn't seem to do a very good job of protecting the staff there. Again, this was in the current situation in which we have a relatively low prevalence of contagion, with social distancing measures and masks in the outside environment.
