I think I understand what you are trying to say, Esna, but I do not myself find it that black and white.
A lot of e.g. the aforementioned non-RPer local allies actually care (as much as anyone cares about anything in an interwebs spaceship game) about the regions they occupy, beyond just "being allied here and wanting pewpew".
And while personal IC relations to non-RPer characters are rarer than those with someone who is an RPer, obviously, they are also not non-existent. There are some (I tried and could name about half a dozen) non-RPers that are important people to Else (as opposed to just me OOC), based on the history those characters share. They know that I am a RPer about "The Republic" and they respect that, I know they are not and do not try to push "drama RP" on them (enough drama in diplomacy tbh).
These guys fit into slots like "a long-time <region> local and a loyal friend", "hero of the Militia", etc. Sometimes, well, better than people who would want to see themselves as RPing such.
