Not pointless at all. Many people walk down stairs much more slowly than they walk along flat level surfaces. Think of people carrying a small suitcase, small children, elderly, or other people who are less stable on their feet but don't want an Ambulift. Furthermore, airstairs are typically narrow with little or no room to overtake when carrying luggage - so one person moving very slowly will delay a long queue of people
