As a conservative libertarian at heart I struggle with government mandating anything. Especially clothing or things that I do with my body. But this presents a real dilemma. Mandating seatbelts (which I despise), or helmets to protect from falling objects or motorcycle accidents, arguably are not the same. If you choose not to wear a helmet, or not to wear a seatbelt, the only individual you're going to harm is yourself.
But, by refusing to wear a mask, you directly increase the risk of infecting others, or becoming sick yourself to the extent that you may have to go to the hospital and interact with healthcare workers, like my wife.
That means the decision not to wear a mask, which thereby infects more people, results in higher patient flow, sicker patients, and ultimately more exposure to the virus for my wife and her co-workers. In other words, your decision not to wear a mask causes harm to others. While that may be debated to a certain extent, if we accept it as a premise that a mask does reduce infection rates, then we must also accept that not wearing a mask increases those rates. Even if by a small amount, it has a huge impact on how much risk healthcare workers have to handle.
So despite my libertarian leanings, I do feel masks should be mandatory. Now, whether that is through a government mandate, or through private businesses that all coordinate and require masks for entry, I prefer the latter. But the reality is people are genuinely medically illiterate. And unfortunately their illiteracy means my wife is put at greater risk. As such, mandating masks it's something I reluctantly accept as a necessity.
The the problem is of course, now that everything has become polarized and politicized, wearing a mask, or not wearing a mask, is seen as a political statement. Wear a mask, and you're a liberal. Don't wear a mask and you're a conservative. Many of my neighbors up here in middle Tennessee, arguably a bubble of conservatives, steadfastly refuse to wear masks because they see it as a surrender to the left. I have to admit I to feel the pressure not to wear one, but after hearing what's going on in Florida where my wife is working as an ER doc, my perspective has completely changed. Unfortunately there is no easy way to convey the fear, the panic, the anxiety, and the PTSD-level stress that healthcare workers are going through down there. If there was, I think more people would abandon the politics and do whatever is necessary to minimize the risk.
