Why do you think it should be 'instead of'? It's quite possible to both wear a mask and get 15 minutes of direct sunlight on your arms. I do it every day.
BTW, while the mask probably helps protect me from you, the main reason I wear it is to protect you from me. So you shouldn't be discouraging me from wearing a mask.

Most masks -- are utterly useless. The home made ones only give like 2% protection and the hospital ones like 50%. People run around thinking they are safe with these and ignore their vitamin D status. Insanity.
Masks have become the new way to shame people and are proven ineffective. They should only allow masks proven to be effective.
Masks protect others from you, as J said. There's a vid somewhere on CD showing a person with and without a mask and compares the breath leaving the person with the mask on, and with the mask off. It clearly shows that masks keep people's breath to themselves much better than not.
Moreover, those with immunity problems of course will want to wear them...because when you're at risk, 2% to 50% is meaningful...not sure where the statistical significance starts in that range, but it doesn't matter. Because even with out immunity problems, having a better chance (2% or 50%...the latter of which surely does have meaning) is still better than nothing. For ourselves. For others.
All the cool socially responsible people are doing it. And the people shaming are shameful and exactly the sort of people that are part of the problem.
"15 minutes of sunshine a day is all you need" is like saying everyone should drink 64 oz. of water per day. That's too much for some people and not enough for others, depending on their size, activity level, the temperature, etc. etc.
If you have not had your blood level tested you have no idea if your vitamin D level is optimal or not. 10 years ago mine was low (in the low 20s), even though I was getting at least 15 minutes of sunshine on my arms and face a day, and I live in Southern California where it is sunny most of the time (I have had the basal cell carcinomas to prove it). Now that I've been taking 2000 iu of vitamin D every day for years, my level stays up above 40 where it should be.
I couldn't care less about the masks; if your vitamin D levels are optimal (>40), your risk of contracting respiratory viruses is reduced by 40-50%. The OP's linked article supports this, as do many other scientific studies. And the drop in risk is not specific to any one virus; it's about how your body's immune system functions and responds to viruses.

Not to mention all the other benefits of having your vitamin D blood level up.
But if the government just said that here and people got the Vitamin D level up -- this thing could end.
At least wearing a mask decreases the amount of 'spraying what you're saying' that some people do.
