I could see if they were writing for a young girl audience, twue wuv overcoming societal hardship even when it is 100% both logical and moral for it not to. But World's End Harem is very clearly written for a male audience, not disney princess wannabes.
Parallel Paradise does it better. Guy gets isekai'd, world of all hot young women... Because they all die when they turn 19. Getting pregnant breaks the curse. He's the only male left on the planet. He's smitten with one bonnie lass, but any woman 18 years of age, he offers to sleep with to try to save them, as he journeys to figure out how to stop the curse entirely. His girl knows he's doing this, and also acknowledges it as an unfortunate necessity.
It's still borderline-H pure selling-on-sex-appeal manga, but at least the MCs know that "last male on Earth" is actually on some level a responsibility, not some funtime background note.
It really is.
