It depends if they are there to pilot or they are there to go outside and build things. Most construction in space at this point is one off, robots probably aren't quite at the point where they can have robots perform any generalized construction required. Of course I don't think we should be placing humans in the loop unless they are required. Also a lot of the ISS work is experiments, each with their own setup and criteria. Obviously at some point this will be solved, but there is still the point of having humans in more places than just the Earth.
