Oh my gosh, you can come up with an imaginary situation to justify a mechanics situation?
I'm so impressed; you should pat yourself on the back! Clearly I was struggling to come up with an RP reason; obviously the issue here is that we need to protect the interests of NPCs against players. That's a major concern.
Aren't you doing the same with trying to justify the state of Terran as reason to get a manual government change? Anarchy is a game mechanic, your realm has not been through it. Terran has had a government this whole time, and thus there has been no anarchy.
