So instead of using the provided BGS and all the impartial mechanics and assets under its purview, all one would have to do to make your alternative workable is:
1) find a bunch of players who are interested in one's vision of an imaginary asset.
2) Convince them to agree on a set of organised, setpiece rules that are entirely self-enforced for possession of the asset that exists only in everyone's imagination.
3) Coordinate some kind of contest where everyone follows the rules.
4) Smile as everything goes off without a hitch where the losing side gracefully accepts defeat.
5) "Interact" with your newly-won imaginary asset in a system with nothing except maybe a fleet carrier in it.
Do you see why this might be a hard sell for people who aren't Calteru?
I see a lot of other groups that have already done similar things. And, actually, I
did do this. I've actually been doing these things quite a bit over the past 20 years or so. You'd be surprised what a simple dice rolling command can facilitate. But this isn't about me, because I have what I want. I went out there, found the group, secured their participation by pitching the idea, structured a whole story around existing mechanics (mostly exploration, given the lore we're using) except there is no "losing" side -- it's PvE -- but it certainly was more commonplace on SWTOR where we didn't have overmap territory capture mechanics. We had to agree on what constituted takeover and control, and Taris in particular was super fun as a result.
If the content and story are what matter most, this is certainly achievable. Several large groups in this game are proof that a concept can be sold to a large group of people that cooperate to make it happen in-game. Warring factions among unpopulated stars can certainly be worked in, and might prove attractive to not just Open players looking for the full player-driven experience but also people in PG/Solo who may stumble upon the area in their versions of space and decide to maintain them. Or maybe a group can be convinced of that, with the right services offered at the right prices in the right places.
Lots of room to work with, provided one's willing to incorporate one's imagination. A creative mind and talented group can work around a lot of perceived limitations -- and have. But it's not for everyone, and for those, I guess it's at the mercy of the developer.
That's... working out really great right now? I mean, the place isn't actively on fire anyway. Yet.
