It also assumes that liquid water and an oxygen atmosphere are prerequisites for life. Extremophiles living on our own planet prove that this is not so.
Maybe this is splitting hairs, but we have evidence that life can exist in such extreme condition. We have no evidence that life can arise under those conditions. I think it's perfectly plausible that it's path-dependent: life needs the friendlier conditions to first develop; once it's up and running with a means of evolving, it's able to acclimatize gradually to the extremes.
If I'm right, then it's still correct to exclude worlds that could never have had the "correct" conditions.
