Which is by the by to the point -- if the rules are there, the amount of effort spent to creatively discount them feels like nothing other than blatant cheating. A sleight of hand.
Note also my response to your second comment to my original -- OP said nothing of it needing to be used before the sabbath. In terms of the eruv, what may be a gentle convenience or exception for a few neighbouring houses, or relations, seems to really stretch when it encompasses tens of thousands+ in multiple city regions. Though I note from other comments regarding Feinsten, if accurate, that some noted Jewish scholars appear to have thought the concept stretched the point too.
I am not an eruv or even a Jewish law expert, but I can assure you though that Rabbi Moshe Feinsteins positions were widely accepted in the Orthodox Community and his opinions are not only well documented and sourced, they are studied today much like court precedents are set. There are obviously differing view points, but in order to disagree with him and be listened to, one would need to extensively show their math and support their dissenting opinion with reliable sources and case history...
In general, the rule of thumb around Jewish law atleast for Orthodox Jews is, "ask your local orthodox rabbi." And interestingly enough, when interviewing for synagogue and pulpit positions, one of the common questions asked of Rabbi Applicants is "who do you ask your religious and halachik questions to?" Central to the faith is collaboration and discussion at the highest levels and if you arent stumped constantly and discussing with mentors and peers, you by default disqualify your credentials to most Ultra Orthodx Jews.
Religion is an exploit of faith to allow power to beget more power, just like any other "isms" like capitalism, fascism, socialism, etc etc.
I wont pretend to understand consciousness or the human experience...but I like to be pragmatic, and from a pragmatic perspective, I dont see the utility of your belief about religion and faith and power structures...its an almost helpleas viewpoint that rejects everything as imaginary and malleable...and I dont see the value in that in my own beliefs and philosophy.
