Its a chicken-egg problem. We can not start with expansive infrastructure. When going west people did not build the rail roads first, they just went and eventually it made sense to build the rail road. Musk has build the ITS so that it is a transport ship that can reliable establish surface to surface transportation. Maybe eventually it will make sense to have tugs and refueling stations in orbit. This will only happen if there is a reason to fly very often. Elon is building the cheapest possible thing that can get the job done. > anything goes wrong anywhere, it's almost impossible to fix or send help when it can only come from Earth Surface. The idea is that multiple ITS will fly at the same time, they will be able to exchange people before landing on Mars if one of the ITS has problems.
