Then wear a mask that protects you. Those do exist. Expecting other people to do something because you have a high risk factor is a recipe for disappointment, notwithstanding any liberty/legal issues with it.
Also, I fail to see the reason for the sudden nationwide mask shortage. The curve has essentially been flattened. Outside of a few select areas the health care system is not overwhelmed. This is the time the healthy people need to start producing antibodies to isolate the disease. If you are high risk like Hawkmoon, or likely to have an issue with a respiratory illness, definitely engage in strict social distancing, and utilize properly deployed PPE. The rest of us need to herd up and start building the immunity.
One Hundred Percent.
With the flu, we aren't asking 98 people to wear masks everywhere so that 2 people don't die from the flu. Now we should ask 96 people to all wear masks everywhere so that 4 people don't die from the virus?
This has been one of the problems with our response since this started. We are going lowest common denominator instead of isolating specific groups. If you are high risk, isolate yourself and order stuff from Amazon.
This virus has already mutated. That means if we're going the mask route, everyone, everywhere has to continue wearing masks (often incorrectly as pointed out above) for what? Forever? Even as the curve flattens it doesn't mean the virus goes away, and high risk individuals are still high risk. There will be more pandemics and epidemics - depending on how they are defined, I appear to have lived through 4-8 of them with no government mandates or lockdowns. There will be more viruses. The world is not a safe space. A free world especially not so. This is getting to be like a city banning peanuts because 100 residents have a peanut allergy.
In the short term (as in, a few weeks), did lockdowns help? Probably. We can't continue them forever though, and in the long term, they will be detrimental, both economically and medically. As Dogmush said, we have to get the herd immunity going or just plan on walking around in isolation suits for the rest of our lives to avoid catching stuff.
