Exactly!
That was the Rebbe's way of saying don't do it while giving the reasoning!
What in the world??
Did you indeed drink your negel vasser this morning?
Do you also think this paragraph about a Manhattan Eruv was written by the Rebbe in hyperbole?!?
The Rebbe suggested many times that an Eruv should only be done in secret. I have never heard
anyone suggest the Rebbe was merely joking about these suggestions!
The onus is on you, please provide a source that the Rebbe wasn't serious about these suggestions of a secret eruv to prevent bring oiver a d'oraysa against carrying.
