While that is fundamentally untrue (they provide a substantial degree of protection

to others) holding uniformed opinions about them is irrelevant in places where it's a legal requirement to put one on when entering a store.
Eg, wandering around in the grocery store AC shirtless might feel nice, but it's not allowed either.
If there were an open-air vending cart, arguments might be made about reasonable ways to do it. But those are rare and when they do exist, usually a bit pricey for a full refill.
