Where do bad papers go to die?
There's always room to publish any paper, even a computer-generated one that doesn't make sense. You just need to target the "appropriate" publication/venue.

Being more serious now, I have rarely seen any rejected work that "just died". For good or bad, the paper or parts of it were always later reused / resubmitted and eventually accepted.

I am not saying that's a good thing, because some papers/ideas/research topics are really terrible and absurd, but too many researchers are usually too stubborn / invested to accept it. Many of them, in fact, have made a career out of this (like republishing the same absurd/non-working idea for decades) and everyone seems to be okay with it.

These days there's really room for everything: publishing is a huge business. Again, it all depends on your standards.
