This is why it is good we have a mesorah from R Aharon.
You do realize that What Rav Aron held was a reshus harabim gamur is certainly relevant today But the considerations that went into weighing the chashashos of 7th st for example vs michshol and saying we have a mesorah in Lakewood 2023 is not comparing apples to oranges, it’s comparing apples to Moonrocks. Rav Aron’s Lakewood had a few families on private way who were living the yeshiva. The chashashos, and the need for an eruv was minimal. Fast forward to the Lakewood of today with tens of thousands of residents who often live in proximity to siblings and parents, commonly walking 20 to 30 minutes for shabbos meals and going out in about for simchas and the like, and the need and opportunity for michshol is exponentially different.
