Not sure that works the way you want it to though as most of these folks are likely younger. They aren't going to die from this.
But you do bring up a question I've had...to me the argument for wearing a mask (to those who would prefer not to) is not to protect oneself, it's to protect others. As a middle aged man myself, I have close to zero fear of contracting and/or dying from this and I don't know many who do. I'm much more afraid of things way more likely to kill me, so I would never wear a mask anywhere but in a closed environment. However, as a precaution to prevent passing it to elderly or at-risk folks, I'll wear one inside and have no issue being mandated to do so. People who fight that, to me, are out of line.
But, I do shudder at the notion that we would try to scare the average healthy person into thinking they need to wear a mask to save their lives. The same people we allow to drive, go to McDonalds, buy liquor or drugs legally, etc. Dying from Coronavirus, relative to many other risks, isn't even on the radar for these people. We can't lose context here.
