Someday after I "retire" I hope to have more time to work on all that.
Tangentially, on a super earth with more gravity, they would have an easier time going into orbit energetically using mass drivers or laser launch systems instead of rockets. And in any case, how big a seed do you really need to make a space infrastructure if you are patient? And the ground can communicate to space with radio or lasers (like for telepresence) which are not affected much by planetary gravity even for super earths.
