Before I comment a nitpick:

Because of the fundamentally broken and irrational nature of how our psychology interacts with the non-ansectral environment, all of our imperfect arrangements will inevitably produce much psychological and/or social suffering and "dysfunction"

While I do agree we are worse off in this regard because of the strangeness of the modern world, there is no reason to think nature wouldn't produce some or perhaps quite a bit of social and psychological suffering even with us being perfectly well adapted to our environment.

I mean we don't expect it to do so with physical pain.
