“Agreed, however, that will be true if that individual is Machmir on each and every Halcha were it is states “Baal Nefesh” should be Yotza all.”
Ummm no. Nobody has ever held that way until you just now. You’re implying that we should just follow the letter of a law, and if somebody wants to take on one chumrah as a nice thing, they have to take on every chumrah that exists? That’s absurd. There are some select things like Rabbeinu Tam’s tefillin where you aren’t supposed to take it on unless you’re known for being machmir elsewhere for risk of looking like a baal gaavah. The same caution does not exist if someone wants to start keeping Rabbeinu Tam’s tzeis. The point being, the baal gaavah concern (which is the only thing I can assume you were going for) is not universal across all things. I’ve never heard it applied to eruvim.
Anyway, we digress. Maskil, if you have the teshuva handy and know the answer as to why he didn’t want an eruv in Lakewood, why don’t you just sum it up so that you can stop us from hitting 100 posts by people theorizing who (obviously) don’t have ready access to the teshuvah. Or is it that you don’t know the answer or have the sefer and your post essentially just comes down to “the answer is out there. I don’t know what it is either, but I’m going to criticize the intelligence of everyone else for not knowing.”
