If masks aren’t used for protection, then hospital staff are not being put at risk by not having them—as we are now told they are.
Sure, they are only one piece and probably a small one at that, but even if they help someone keep from touching their mouth or nose, that is a help.
The hospital staff will know how to fit them properly, and are in a high-risk area.
An average person is already keeping some distance from other people, and is more likely to pick up something by touching a surface touched by someone who sneezed into their hand, and then rubbing their eyes or near their mouth or nose.
That’s why the focus is on not touching people or things, NOT touching your face, and using disinfectant whenever you DO touch things.
