You know, the most the Empire did was go "hey, this is my side of the galaxy. If you wanna come over here, we got border control." They didn't paint everything black, gray, or white, or whatever color floats your boat, sure, pink. They also put Ships in sectors to show their authority. They also didn't bring EVERY ship they owned to one battle because they were keeping a HOLD on that patrolled/protected territory.
And you want to know a problem with "who owns what confusion" issue? It doesn't matter. On this board, it just, I'm sorry, I'm really sorry, but it couldn't matter any less. No player is forced to interact with another. No player is forced to interact with any faction. If a jedi wants a private thread on a sith capital, they can do it!
I'm not suggesting you ignore groups of players, I'm saying it's done all the time! Intentionally or not. If I want to interact with a faction, I look them up, see who I can talk to, communicate and discuss how a thread should go. Otherwise, the information is a given. Doing a rebellion, dominion, or invasion? It's known what the territory is.
EDIT: A Faction can keep its own records, it's not hard.
Territory:
