I once watched video of a 180 ft water storage tank falling over - it was impressive, and caused a lot of damage to the surrounding area.
It’s hard to imagine the catastrophic effects of a +/- 64,000 ft tall tower toppling over.
What happens if you get stuck halfway up? You’ll need a parachute and O2 bottle........................
Dr. Octopus once threw Spider-Man against a water storage tank on top of the Daily Bugle building, and the water drenched J. Jonah Jameson.
With a traditional structure, yeah, that would be disastrous, but if the structure is basically a bag filled with gas, with some struts to keep it rigid? If it’s going to fall, it will rupture on the way down, the gas will escape, and only a fraction of it will actually hit the ground. I’m sure it would still be a disaster, but not nearly as bad as a 12 mile high traditional structure collapsing.
