That is not how your comment reads. It reads like you think every trait exists as an advantage and propagates because it is a benefit. Plenty of traits propagate as side effects, which is how their comment read to me.
Not really, and I think it’s because any unnecessary trait is an extra cost. But you can have your belief or even think we were magiced by an all powerful entity
unnecessary traits might not always lead to extra cost, and even then, the extra cost might not always lead to extinction.
the extinction usually happens when a trait that represents a disadvantage in a sufficiently heavy competition for survival. If the competition is low enough, the trait may survive.
