Reply To: New Brooklyn Eruv: Time to Accept?

n0mesorah,
“Rav Moshe was a Rav in Russia and a Rosh Yeshiva in Manhattan. You can take all your useless halacha and throw into the any of the bodies of water in between. None of this works that way.”
By the way, my argument stands. The Ramban (and other Rishonim) asked on shitos Behag/Rashi that such a chiddush should have been mentioned by Chazal. But we can’t argue that at the minimum the Rishonim should have mentioned Rav Moshe’s chiddush that shishim ribo is conditional of five times the number of people over an area of 12 mil by 12 mil. Furthermore, Rav Moshe would not issue a psak din barur, because he agreed that even the poskim did not mention his chiddush. This absurdness comes from those who never learnt the inyan.
