While I fundamentally agree with base building in a general sense, your suggestion seems far too much like it belongs in Eve online rather than Elite.
Adding in proper in-depth persistent NPC plots alongside minor faction colonisation, station construction and colony/station abandoning in a fully dynamic manner on the other hand... I personally would find it more interesting to attempt to politically wrangle a minor faction into setting up a colony somewhere rather than just entering into another grind to build it myself.
As an alternative to player-owned assets, it would make far more sense and be easier to manage/implement if we could instead rent some commercial/industrial halls in existing stations to fill with our own stuff if we have sufficient reputation.
