I don’t understand the conclusion at all, and why Rav Zilber assumes the Rambam and the Rashbam disagree. If anything, the Rambam disagrees with the Gemorah in Bava Basra (that there is some advantage of going in a different direction), not the Rashbam’s P’shat.
??? ???? ???? ?????? ?????, ???? ??? ?????? ?? ??????; ?????? ?????? ????? ??? ?? ???? ???? ?????–????, ??? ???? ???? ?????.
Even according the the P’shat of the Yad Ramah, all he is saying is that if one does stare, it is more his fault because he took that path.
Besides, the whole Gemorah’s question seems to be nonsensical according to this P’shat:
?????? ??) ????? ????? ????? ??? ?”? ???? ?? ??? ?? ???? ????? ????? ???? ??????? ?? ?????? ???? ??? ?? ????? ???? ?????? ??? ??? ?? ????? ???? ?????? ???? ??? ????? ????? ???? ?????? ???”? ????? ??? ????? ?????
The whole Gemorah is talking about an ???? ?????, not a ?????
