You're assuming perfect assimilation happens. Otherwise you simply have a colony. If the colony outstrips the natives, they change the culture and eventually the governance of a place by right of conquest. Then they can change names and there's no denying it.

States encompass territory, but nations are defined by their people and culture.

They don’t even need to achieve a majority. Look at New York City or urban New Jersey. You think those places are the same as they would have been had they remained British and Dutch?

It's been a ... little while since NYC was Dutch. Let me put my tricornered hat on and think carefully.

"Perfect assimilation" doesn't seem like something that actually happens in reality.
