ETA: This isn't an either or situation. You wear your seatbelt and drive safely. You can argue which would save more lives but not one over the other.

was presenting it as an either or situation. I was responding to a poster who claimed that masks are "not that effective" and the only way I could imagine him seeing that somewhere was in an either/or discussion. So I started with that, but tried (not very effectively?) to segue into the more comprehensive answer you gave.
Y'know, the old "Yes, and..." response.
