J. again iwm sorry fot the misuderstanding, although i realise why you misuderstood me. let me explain.
.
The shulchan Oruch lists two options for what defines a reshus harabim de’oyraisa, who in our context a place where an eiruv does not help.
1) any road 16 amos wide
2)yesh oimrim, a road on which 600,000 travel every day.
.
Although the pashtus in mechaber may sound like the first shita, as he refers to the secod as a yesh oimrim, nonetheless, the mogan Avraham, Taz, and Mishna Berura, all clearly state that one who chooses to rely on te makilim ??? ????? ???? the Taz further adds that this was indeed the minhag.
.
It being that there is no road in london which reaches that amount it may seem obvious the room for kula.
.
At this point, both the Chazoin Ish and r’ moishe throw a spanner in the works. The yesh oimrim in the mechaber is based on Rashi and the Mordechai, yet they do not refr 600,000 every day, rather to a town of 600k. As such they suggest that roads in such towns may have problems.
R’ moishe however carefully defines this, howver. (orach chayim 4, t.117&118) He points out thta in the midbar there was more than 600k, there fore one needs to take into the account the wider fmailies of the diglei midbar. He also limits it to roads that are built ot serve most of the town. This was the bsic reasoning for ossering the Brooklym eruv.
.
R’ Roberts, R’ Padwa senior zatzal, R’ ehalpern [S’dei Elchonon] and the michas Yitzchok, all felt that this is a problem in london too.
.
R’ Roberts would not expect his kehilla not to shave, etc…, he however feels that the eruv is a de’oraysa. He was however pointing out to those hwo may have heard to the contrary, that nonetheless they should take his opinion into account due to the severity of the matter.
