> not be subject to the whims of orbit.
Just because something does not orbits a planet it orbits a start, if not a star then a cluster, or even the center of a galaxy. Even galaxies are in orbit of something.

Weight always an issue due to propulsion.
Plus all the ships assembled (or just one hueg ass ship) needs materials to assembled from, and that needs transportation too. Or if the materials are produced in space that needs the whole production line to be set up.
