Richmond:
The reason it comes across as n0m is saying is because you keep telling us there are these mysterious sources out there that we would all obviously know about if we weren’t so clueless. Then, when we bring actual sources (even ones that assist the meikel stance), you just double down with the same stuff without getting any more specific.
In the time you’ve taken to countlessly allude to these “halachic mechanisms” without ever naming sources or explaining them, or even making any attempt to reasonably prove their existence, you could have easily just told us over the information that you allegedly think we’re all lacking.
People here are either going to conclude–as you wish–that there is some secret halachic mechanism that is suspiciously left out of all publications discussing modern city eruvin that you are suspiciously unwilling to explain, yet somehow expect all frum yidden who have “done their homework” to know about.
Or, we could conclude that there is no rabbit in the hat, and that you have no idea what the new eruv is relying upon, and that you’re simply talking in circles with no real answers.
If we must be dan l’chaf zchus for anonymous forum posters, then maybe we’ll go with the first conclusion. Otherwise, we’ll go with Occum’s Razor: the simple conclusion is probably the correct one.
