Don't need it, but is it good economic tradeoff
There is already power available and some infrastructure and docking facilities. There is a little bit of economy of scale if the host countries have some research going on with some astronauts being transported to and fro. I am also very pessimistic about NASA manned efforts and plans, but I was just wondering if not some use could come from the white elephant to help bootstrap the tourist industry.
I agree the cost to work through NASA might exceed the gains made leveraging the infrastructure, but that is why I was asking if anyone has seriously done a study of this from the commercial standpoint.
