Look, I'm not arguing that it's going to work at all. I'm not an engineer and don't pretend to understand all that would be involved in even attempting to make something like this a reality. But it is called a counterweight for a reason. I would think that it would help to create an equilibrium along the length of the structure, but what do I know?
It's a colossal undertaking and, like I said, if I'm alive in 2050 I'll be turning 94 that year. So I don't think I'll have much to worry about as far as seeing it built.
