Heh, to be honest I can't remember a lot of that! But you're right, Bell's Theorem isn't the only expalantion for why entanglement is "spooky", since Einstein said that long before the theorem even existed. But I think it's the simplest approach for explaining to a lay audience without a lot of extra ideas or "you just gotta believe me on this bit." And I think it's what definitively killed local hidden variable theories.
