I think he was saying that even though we don't understand something, and think it's irrelevant nowadays. The chachamim would have built that exception into their gezeirah. The fact that they didn't is just something that we have to accept whether we understand or not. Like doctors...
I cant say any thing on this thread without being accused of bragging. So, for the record, my chavrusa is a noted Rav and Dayan and deep thinker. My ideas are not shots in the dark. Nor are they unfounded, stam yaynam was not initially accepted in sefard, in italy it was noted (I cant remember who, might have been rav ovadia bartenura) that in one city they werent strict with yayn stam but they were strict with women going to the mikva and in another city it was the exact opposite.
Your co-relation is really silly, that would be akin to saying, we should give every one polio vaccinations.
Halacha is not about blind obedience, there are a few reasons for stam yaynam but by and large its illogical.
