Health,
I agree on testing, but we are talking about people, especially from the stubborn Jewish community. For those who are not going to test (and many will not), they should isolate.
The Talmidei Chachamim I know always test after coming from a crowded Jewish community before mixing up with their congregation. It is pretty easy right now, $20 per home test, I believe. I am reading that Europe now provides these test for free, but Brandon did not dare doing it and is trying complicated schemes like asking people to submit receipt to insurance. This will not increase use.
