In short, CV19 is not something you want to catch. It is not flu. It does not behave like flu - influenza does NOT attack the endothelial lining of the blood vessels (which causes some of the worst effects). This idea that CV19 is "just another flu" really needs to be laid to rest. It really isn't.
All perfectly valid. But as we can't eliminate it, and as a significant amount of people can only avoid it, masks aren't 100% effective and social distancing has to be balanced with various other issues such as child protection, psychological damage and economic hardship, the bottom line is that we need our health services to be able to respond and help those most seriously affected.
Therefore the best position is to try to slow / reduce transmission rates.
