Nature does not measure things, has no purpose and no goals, success nor failure.

Imagining success, failure, and purpose is psychological projection.

On the other hand, the extiction of our species for not-reproducing would be quite a failure even on our own metrics.

So it's not like we're some higher-dimensional ethereal beings, not tied to evolution and our natural fitness, with relation to our successes and failures as a species (and even as individuals).

To reverse the "psychological projection" trope, it's just that we learned throu psychological denial to ignore those aspects most of the time...

No - evolution doesn't place a value (or worth) on reproduction at all.
