The time we spend on this subject is a perfect illustration of the main problem with the Internet age - We are drowning in information and starving for wisdom. Many good points are made here, the mask comment by Salmo is one of the best. If masks are so ineffective why do hospitals and medical clinics use them? The no action alternative is a red herring. It's unprovable one way or the other. Norway was probably the prime advocate of the no action alternative. As you can see from the following link, Norway was about halfway in the list (based upon death per 100,000). Certainly better than the US and most European countries, but worse than others. And this list is a good piece of data for this discussion. Of course some will say that the information is bogus. And a bunch of people believe Trump won in 2020 and that the Easter bunny exists. In all cases, I would ask for proof. https://www.worldometers.info/coronavirus/
