I think people are focusing on the wrong thing. The Final Day is simply ONE of the MANY ways a star can meet its end, the Endsinger is not really the final boss. In another word, they are not the point of the story. Think about it, by the time Venat sundered the world, the final day was already stopped. What she was trying to averse isn't the final day, but the ultimate end of mankind.
Elpis story was there wasn't merely for us to learn the nature of final day, but also to show us (the players) the fatal flaw of the Ancient society that would serve as the basic for Venat decision. Specifically, that flaw is the apathy toward life. While their indifference toward the creation is obvious, the subtext also showed it applies to all life.
Then, before her trial she told the party Meltion is a place where emotion and memory reign supreme, to which Alisae ask if mankind is truly powerless. She answered by address each of the Scion. On the surface, it looks like she merely recounting their lives, but once you put it together with the report by Metion and what she showed you in the final dungeon, Hydalyn was also drawing parallel of the struggle that spelled the end of those dead world, and how now the scion (as representative of mankind) had shown the will to overcome those.
Of course, there is nothing taken for granted. That's why the moon was created as a contingency. Even during the trial, she said we either show the will to overcome the trial or they must leave and never look back. She sacrified everything not for "assured" victory, but to make a bet on mankind's potential. Now, if you want to argue the merit of her decision, or whatever it's justifiable then that's up for debate. But I want to point out it's plenty logical, and definitely not simply based on her bias about our 1-side story.
