So then why not shut down today? If it’s so vital and necessary
Politics. Same reason Israel reneged on closing shuls for Yom Kippur.
This whole line of argument is absurd. You specifically, and many people collectively have argued against the need for restrictions at every turn.
How would you have felt to have constant sheriff presence outside every shul, school, and wedding hall for 2 months? You would have screamed "herd immunity" and government overreach.
The city tried it your way, but unfortunately, the facts no longer bear out that there's herd immunity. So I'm really at a loss for what you would have wanted to have been done differently.
