This may owe to a confusion on my part. I understood from the title of the post and some of its parts (incl the last par.) that the OP was advocating elimination over reduction (ie, contrasting these two options and picking elimination). I agree that if reduction is an option, then it’s still ok to use them in explanation, as per your dollar example.
