I don't know what to tell you if your takeaway from Elpis was that the unsundered were significantly worse off than the sundered. Matter of fact, we're rather explicitly shown that their primary issue is lack of inspiration, which certainly seems the preferable existence to one that still involves war, homelessness, sex trafficking, etc.

Emet also never said they didn't have problems, only that their differences were insignificant next to all they had in common. Were they as perfect as you claim he presented them as there would be no need for the seat of Elidibus. Plus, he's not wrong. As said in the NieR crossover, "Their pitiable lives are fleeting. In the simplest of ways, they die and die." The Ancients "lived nigh for eternity", so from that perspective it is providing "the greatest amount of happiness and the least amount of suffering in the long run".
