Not true. See my post #247
I just noticed that even forces that locally cancel out can still have a drift that grows with the square root of the time. Lots of small impulses impart Brownian motion to things. What I was wondering about is how beanstalk handles drifts in the Earth's axis of rotation. The equator isn't exactly constant otherwise UT0 and UT1 would be the same. Perhaps these are small enough to be corrected by gyroscopes.
What about wind? Few places are really quiet. This would seem to be a problem for the root of the beanstalk.
