That's fair. I'd missed that one.
I'd argue that the constraints given simply make the quest chain longer and more complex, possibly involving re-colonising the system, building out industries, establishing self-sufficiency, warding of threats, recovering lost ships, blueprints, and the like.
A single upstart with good ideas and someone, the player, to do the massive amount of grunt work required, could potentially achieve something.
I'm not saying that it should be done, only that there are ways to make it work if you wanted to, even given the core lore of Kassadari as a failing polity.
