We already had this conversation earlier in this thread, They do not represent large populations. The context matters too. None of these uncontacted tribes are influential in global affairs or, as aptly described "in contact". To say that Limsa + Gridania + Uldah are in the same league as any of the examples mentioned is laughable, in fact, they are a global super power at this stage. Not only did their combined forces alongside you beat back Garlemald but their alliance is the strongest on the planet when you factor in they added the East, Ishgard, and Radz as allies.
In this game, and as far as the map goes, we have no known enemies anymore and everything is under our control. Even the beast tribes settled down and have fought alongside us when needed.
