If everyone follows those rules, where is the aiva?
But like you said, it's probably unlikely that people won't bend the rules, which is a sakana and aiva problem. That slippery slope argument was the reason for the original psak.
So let me see if I have this right. Hatzolah can respond to an emergency call on shabbos to a sofeik pikuach nefesh even if you know its a goy because of aiva. We can have minyanim, in front of a goy's house (this is going on on my block every minyan and has caused the goy to come out cursing and call the police several times) and we dont worry about aiva. What is going on in Boro Park is not porch minyanim It is street minyanim with people congregating from half a block away standing six feet apart sometimes. Strolling back and forth most times. Congregating way less than 6 feet when there is kriyas hatorah. But
@KSMH was right all along. I wish I could video what goes on here and what went on here all yom tov.
On my block alone 3 neighbors lost their fathers (one of whom davened outside with a minyan and has his bar mitzvah age kids strolling all over the block), one lost his brother (He serves as baal tefillah of the second minyan on the block that goes on at the same time as the first one) and an old lady died at home this morning from presumed COVID. We also have sectarian minyanim...Gur chasidim, whose Rebbe has by all accounts been quarantined for at least 4 weeks davening alone insist on davening with their own minyan becuase "we dont say all the things that are said by other people."
THIS IS JUST SHEER INSANITY!!!
