DaMoshe: Not to negate your point, but it’s good to be aware that the current allowances for those living together are because they’re not ready to separate families like they did in China. (Which means separate facilities for those exposed and those with the virus.) This may be one of the reasons the Frum community is being hit harder. Larger families (yes even under one roof) equal more potential for infection.
I’ve seen video footage of porch Minyanim in condo/developments that seem okay, but I can’t vouch for its safety.
