The analogy is garbage.
You're suggesting the Rebbe didn't no how to take a stand and say no?
Why are you refusing to answer my simple questions?
The Rebbe knows exactly what he's doing. He also says various things that we don't necessarily understand (just go to a certain locked thread for examples...). It is not for me to explain WHY the Rebbe posed it the way he did, but I have no doubt that the Rebbe knew when he said it to a Lubavitcher that it would be understood (and acted upon) as "don't erect an eiruv" or "don't get involved with the Melbourne eiruv".
And it is not me suggesting that the Rebbe doesn't know something, it is you who seem to think that you understand and know exactly what the Rebbe wants and thinks, and if it doesn't fit your logic, you just reject it.
