That assumes that everyone is capable of walking on an escalator. I, for one, am not. I get vertigo, and am on the brink of a panic attack for the entire duration of my ride. I can barely step on one, let alone walk, particularly when going down.
I do look for an elevator whenever possible, but there are times when one is not available and I have to work myself up to the task. I have to grip the handrail with both hands, and focus on a point on the steps themselves.
I'm sure there other issues that people have - like being able to walk but not climb - that would prevent them from being able to walk. Therefore, it's best to have the option to stand on one side and walk on the other.
