What's the point with that quite lackluster story in Endwalker?

[Brinne]

Acting as if a life without suffering is bad or makes people weak begs what the alternative should be: should people constantly be striving to make every aspect of life worse, just for the hell of it? If there are no sources of suffering and terror, should we make our own until we eventually get used to that, and then make something even worse just to make sure there's still a prerequisite amount of horror?

I mean, this is more or less exactly what Venat did, so the answer is unironically yes, apparently?

I guess we're supposed to assume that their world had eliminated any need or worry about such things, but how or why? That's the thing: the story tells us they achieved a perfect "paradise", but glosses over exactly what that means.

I still have a strong feeling that EW came out the way it did in part because the devs were determined to make it as positive and encouraging for the player as possible, given their acknowledgment that so many these days are having a difficult time--but then when you start to think about it, the ultimate message of "things may be hard, and you're a cool and strong person for living in these conditions - but also, did you consider that if your life was better, it'd actually suck?" seems... incredibly tone-deaf.
