The problem I see is that walking down stairs is pretty easy and most people can manage a number of floors without a problem. Walking up stairs is a different situation. Many people cannot walk up one or two levels, let alone the number of levels proposed. I think you would need tunnels from several levels going in several directions to escape platforms or safe rooms with elevator or crane access.
Some people claim that the UNIX learning curve is steep, but at least you only have to climb it once.
