So light is an easily solvable problem as are windows. We can simulate views out windows with television screens that project the outside and the light with actual light from the outside using light tubes and bulbs. These aren't insurmountable problems. You also wouldn't have to worry about cleaning windows or breaking them, you'd have storage for vehicles already built into your top layers and you already have to move lots of dirt in building skyscrapers, but you usually can't build parks on top of skyscrapers.
