If everyone had to wear an N95 mask we'd need to permanently shut down the entire bar & restaurant industry, given that the masks are obviously not doing anything when people take them down to eat and drink. That would be millions of people out of work, tens of millions more permanently without the enjoyment of eating or drinking out, etc. I don't mean to sound curt, but society is simply not willing to accept that, sorry. We could lower the speed limit to 15 miles an hour for the entire country, including on highways, and that would save a ton of lives, right? We as a society are just not willing to accept that level of inconvenience.
Seeing as you'd like to make everyone else wear masks, could you rig up a closed-circuit gas or oxygen mask for yourself when you go to the grocery store? That way you're literally not breathing the same air as others, and it'd be literally impossible to get Covid. If your response is 'it's inconvenient for me to wear a gas mask and oxygen tank'- well, that's how the rest of us feel about permanent masking
