I think you just missed the nuance.

GP said "the masks most people wore", which is not to say all masks, but rather suggesting that the majority of masks that real people were really using and how they used them amounted to nothing.

> What about seat belts?

If it helps (though I never met an analogy that wasn't rotten on the inside once dissected in debate) an inadequate or improperly worn seatbelt can be more dangerous.
