Keeping stuff in space has a maintenance cost - both station keeping which can be relatively cheap, and maintenance for any space trash collisions. Most importantly, there is no commercial space station to move people and current starship test articles are not fitted for passenger transport nor low earth orbit rendezvous. It's a long road from even a properly working Starship towards this goal.
