“Please stop vacillating between the two distinct arguments, that Rav Moshe would still oppose an eruv”
I’m not. I keep making one point and other points keep getting brought up. Regarding THIS SPECIFIC POINT. Nobody knows what Rav Moshe would say today, because he is not around to ask. Unfortunately for us, he is dead. My argument as to who would be the most authorative person to tell us what he would say today is his closest talmidim, and in this case, that talmid happens to be his son, R’ Dovid. therefore, I am arguing that if anyone has a “right” to claim what R” Moshe would say today, it is R” Dovid.
