“As for RAv Moshe Feinstein, I implore you to learn his own words and tell me a coherent heter for Queens.”
Go to the KGH Eiruv’s website. There’s a hand-written letter of approval on there from Reb Moshe. I wasn’t really able to read his hand writing, but you’re welcome to give it a shot.
In any case, the fact that you don’t personally understand why he differentiated between Queens and the other boroughs does not mean there is no real reason. He was matir Kew Garden Hills and asser Brooklyn. Those are the facts.

“I really can’t make sense of your post.”
Having a little trouble also, but I think he’s trying to make the argument binary, meaning there are those who hold by the machmir definition of a R”HR like the sphardi rishonim and the stam halacha in the S”A which would disallow all city eiruvin, and there are those that hold like Rashi and the yesh omrim in the S”A (as we almost all do today). This isn’t really the case with this who debate. We’re all operating within Rashi’s definition otherwise there would be nothing to talk about. The claim is that Brooklyn and Manhattan are reshusei harabim according even to the meikel shittos.
