Because the author is clearly the type of person that hates people. That is pretty common in anime. Miyazaki talks about that.
Do you know what that means? Here, I'm going to explain for you.
You get an old anime like Cowboy Bebop and you see that the animators were looking at real fucking people to draw their characters. They were looking at actors, or people, how they behave, and drawing from that.
Frieren? The author is an otaku that hates people. You can see that Freiren characters are based on characters from others animes, who were based on characters from other animes. It is a fucking incestuous children of an author that hates looking at actual fucking people. A sea of tropes.
What is wrong with that? Well, if you want to shove your average shounen brainrot, nothing. People can enjoy fast food and mcdonalds, that's okay. But, if you want to be the series that "deeply analizes the psyche and suffering of living that long", fuck off. I don't care about how your anime trope feels about being an old bitch. She's not real. Come back when you are able to draw characters that feel like real people.
