I'll bet these palms really don't even budge [apart from during
earthquakes and landslides].

Good points. Still I can envision a palm on a hillside being dragged
gradually downhill and being either propped up or being pulled upright by
roots (likely only one or the other mechanism, not both). But this is pure
conjecture. Even at best it won't be a large scale phenomenon (either in
distance covered or number of plants involved).
