Durst just embarrasses himself amongst architects, developers and engineers, all who have built and maintained structures of exactly the same size and use around the world. By saying it is impossible, it makes him look like a fool.
As pointed out many times in this thread, the CN Tower has a fiberglass radome over its antenna reaching to 1815 feet. It was not put in place by a crane but hauled up in pieces using the elevators and external hoists. (The cranes had already been dismantled by the time the radome went up.)
Furthermore, that radome has stood for nearly 40 years without damage nor major repair needed.
This post keeps showing up no matter how many times the subject comes up:
