As a scientist, I have seen a number of studies that do show that 1) Covid is spread by aerosols and airborne droplets, and 2) Masks (at least most decent ones) do help prevent the spread and inhalation of covid in the air. So I agree that they can be useful, and mandated in many places. But I also think that some places have gone nuts, by asking people to wear them when alone (or with only family members) outside, in their car, and many other places that people are not near anyone else. I have seen cases of disease spreading by people being tightly packed indoors, but few cases of people catching it from just walking, etc outside. So I don't mind wearing a mask to work, shopping, in crowds, etc, but do think mandating them outside in all cases is pointless. (

As to countries trying to eliminate the virus, a few did it for a short time, but almost all have failed or will fail, including a remote island of 54 that now has it. As Sunt said, we can flatten the curve, but it will be hard to eliminate it. I can see older people staying home if retired or able to survive on savings, but most of us need to eat and pay our bills somehow, so we have to work for a living. Until a good treatment and/or vaccine come out, which may take a while, that requires some of us to take risks, but they are not so bad for younger, healthier, people. If they would just let kids to summer camps and colleges, catch the damn thing and then stay put for 3 weeks, it would run its course, most of the kids would get it and be over it, and then they could go back to school with little hazard to most people, and life could move on. I keep hearing about 100's of college students catching it, and have heard few of them getting very sick. More kids die in college from alcohol than will die of Covid, I would bet. I agree this is not a trivial disease, and people with obesity, health issues, and older age should stay home (maybe go on a diet as well, including myself), and there are risks, but trying to isolate and quarentine 320 million people for over a year will cause far more issues than Covid in the long run.
