Given any entity that yearns for its own survival (a person, a business, an organism etc): does it matter whether it's means of observing the world are imperfect if said means are good enough to ensure it's continued survival?

Is good enough all we're striving for? Is treading water the pinnacle of human accomplishment?

For a lot of businesses, yes - that's exactly what they're striving for.

I think what's confusing to me about this and your previous point, is you mentioned this inability to access objective reality outside our own subjective experience, but now appeal to a shared human experience (i.e., there's a general human accomplishment we should all be working towards that goes beyond our subjective experience). I can understand one or the other, but it seems there's some tension between those 2 views.
