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

[Rulakir]

I myself lean towards conservative/libertarian views (and that would entail upholding/preserving certain values over a status quo per se)

Yours is a better definition. I tend to be fiercely libertarian myself, so as soon as Venat infringed on everyone's fundamental rights to create her new world order it was a big Hell no from me.

Furthermore, if I wanted to be more harsh on the Anicents, and especially those that became Ascians, I'd call them entho-nationlist.

Well, if we go that route then Venat is guilty of racial cleansing. She eradicated the Ancients as a race, including the complete erasure of their history.
