I totally agree with the OP, right now Zoner battleships cause more trouble than they're worth. If ones roleplay is good enough to justify flying a huge mobile freeport / colony ship, then you might aswell SRP it.
Gather materials, create / acquire blueprints, get some interactions with way more factions going, and you'll get one with enough effort.
If not, nerf the Zoner battleships to the bottom so that they're the worst ones, and completely unusable for anything else than RP.
