Aparently, I’ve conflated Level with Plumb, the walls cannot be parallel and plumb. Due to the curve, the center of gravity for the walls would require them to angle in slightly together or not be plumb.

      The idea about the really long building though is that gravity pulls down at a different angle as you get further two points further apart Even if the pad was absolutely straight, If you had a 2 mi long building the walls would no longer be plumb* at the ends if they were parallel.
