Keep in mind the limits on the level of civilization smilis have though - the Pompeii smilis are very advanced for their species and they're still a very basic society, more like settled hunter-gatherers that are starting to make forays into ideas like government and bartering. Other smili groups would likely be nowhere near that level. ;3
Is there any summary of what is known about the Pompeii smili government so far? For example, do they lay taxes on individual smilis or their goods, do they maintain a census, etc?
