Whether it makes sense to wear masks in public, if you are already keeping your distance, and whether it offers you any protection to wear a mask of your own, is debatable. It probably helps a little.
What's not debatable is whether you should wear a mask around immunocompromised people, like many people hospitalized for cancer treatment. Staff wearing masks and PPE is a year-round life-long practice for hospital staff caring for immunosuppressed cancer patients. Even if Pence were swabbed and negative for Corona that morning, it's a dick move not to wear a mask in that setting. There are lots of other things that can be passed around. People with immunosuppression due to chemotherapy are told not to eat raw fruits and vegetables, to avoid crowds, avoid picking up dog poop, etc. etc., regardless and not specific to covid or coronavirus. If you don't have an immune system working, the regular common cold can become a life-threatening pneumonia easily.
We don't know if the "patient" in the photos was immunocompromised or not, but if you're visiting the cancer center these days, you wear a mask. Unless you're a psychopath or maybe just a douchebag trying to score political points in some way.
Oh, and "Nature" doesn't care if you live or die, or what's best for you. You are grist for the mill as far as Nature is concerned. If you are "cautious" to add man-made "improvements" to evolution, you should probably forego heating and cooling your home, using electricity, using pharmaceuticals of any kind, and training with barbells, to name just a few unnatural things. I don't recommend this, as most of these "unnatural" developments are fantastic, but if you think that wearing a mask is somehow a crime against "nature," you are just scratching the surface. "Natural" life expectancy of human beings is probably around 30. Personally, I'm in favor of using any and all reasonable means to surpass that by a long way.
And if your mask prevents the free flow of atmospheric gases, it's not a surgical mask. It might be a plastic bag. Please follow the label instructions.
