In the future, there will probably be a way for realms to modify their government systems, and possibly even a complete removal of the strict types. But that's for the future.
Right now, we have what we have. It's a functional system that Terran can use to change it themselves. Yes, it involves some risk. But in that way it gives other people in the realm the opportunity to participate and advance plans and schemes of their own, rather than have one player unilaterally, and without risk, make that decision for the realm.
For some reason the players in Terran (or the only one we've heard from so far) don't want to use it. Instead we hear "we've already RPd that it happened, so please change it for us".
You've got a system. Use it.
