Yeah, that's the point. We are constantly having to argue over the what the rules should be in any case where one of the "tile-based systems" does not translate from the 4X game in its author's brain to the Minecraft world we are all roleplaying in, or the infinite possible scenarios that could happen in text-based roleplay.
For instance, say there's a rebellion in tile X. Group A is fed up with the leadership of Group B. Is tile X now at war with itself? Who is allowed to move through tile X to get to another warclaim somewhere else? If Group A wins, what happens to Groups C and D which were neutral in the rebellion? Are they vassals of A, or does tile X get redrawn?
But I guess since it's so important, who's the PRO on tile X? Clearly it can't be a member of Group A or Group B; how could that possibly be fair? So I guess there's no PRO now. Every "system" that depends on there being a PRO has to either be suspended or rewritten to cover this specific case. There was a point a few maps ago where you literally were not allowed to rebel because the staff could not figure out how it was supposed to work.
LotC's rules are based on such fragile and expensive abstractions that when the war rules need to be rewritten, there's a long period with no rules, and no way to resolve conflicts. And you're asking me how we'll figure out who gets to go to war with a house in the freebuild or what builds are allowed? I think we'll figure it out!
We don't need to reach for a hypothetical. There is a 100+ reply forum argument going on right now that started because there weren't specific rules to represent the roleplay agreement the high elves made with Caurost. This is why we're arguing about freebuild. It's not just because we like placing blocks. It's because the rules and """systems""" have become so bloated and overcomplicated that the Admins can't seem to figure them out.
