Typically buildings with paternosters will also have elevators too, the paternoster just decreases the total amount of floor area that has to be used ferrying people up and down. In the one I saw, the elevator was literally on the wall opposite the paternoster. Disabled people aren't the only ones who can't use paternosters; they're also unsuitable for moving bulky or heavy items between floors.
