What about those people alive now that were never Amaurotines and didn't feel that sense of profound loss when exposed to the star shower? What we saw was a sliver of a whole world that we're just beginning to get glimpses of so unless we get more information the ethics of the Rejoining are going to come down to one's feelings on the actions of the post sundering Ascians.

We do know that Zodiark would require additional sacrifices to bring back those who made the initial sacrifice. We know that there were Amaurotines who felt that enough had been sacrificed and to sacrifice new life was unethical. We know that Zodiark was a reprieve, not a long term solution, from the Sound. We know that the majority of those in Amaurot supported the Convocation, but you're also looking at immortals who were facing the possibility of true death for the first time.

For all we know if the rejoining were to happen than we'd be looking at the end of Amaurot all over again since Zodiark wasn't a true solution to whatever was happening. At the end of the day, we just don't have a full enough picture of what happened yet.
If the world was invaded by something else, the Final Days isn't evidence of it being unstable - it's evidence of that thing rendering it such. For all we know it could’ve been an alien life form(which is starting to seem likely). As far as Zodiark not being a permanent solution, that’s not something we know. It’s simply something Venat surmises. He did what he was meant to do. It’s not proven whether he was a permanent solution or not afaik.
