What's the point with that quite lackluster story in Endwalker?

[Raoabolic]

The Allagans are gone but G'raha's Miqo'te tribe were still there and came there after being displaced themselves. The Garleans aren't even from there either and came from somewhere else before they were displaced. At least one of the proto-Garlean tribes created the city of Goug before the city exploded and they had to move.

Then if we allow everyone to claim land on a first come first serve basis then Limsa has some 'splanin to do. Besides, if that is how things worked then we would have a sweet game of musical chairs with land, lol. At this point the Garleans are displaced and the Miqo'tes can claim their land back. Would that give the existing Garleans casus belli to then take back said land? Now that I think about it, that sounds like a pretty sweet new storyline the game can go but I know the current writers won't touch this angle of the story with a ten foot pole, lol.
