Profound pontifications above from individuals who, I suspect, do not have M.D. degrees. Here's a question to ponder: if you are having open heart surgery are you comfortable if your surgeon decides not to wear a mask, gloves, and surgical cap? Face masks (cloth at the time) and gloves were introduced in surgery in the late 19th century because surgeons observed a decrease in post-op infections when face and hand coverings were utilized. While the use of a mask is only partially effective in helping to protect an individual from contracting the Coronavirus (or any virus), a mask is extremely effective in helping to prevent the spread of infection to others. And, regarding a vaccine, just as we do not have a bNAb-generating (broadly neutralizing antibody) vaccine for AIDS, we don't know if one can be produced for Coronavirus, particularly a vaccine which would confer lasting immunity. An effective and safe vaccine may not be forthcoming in the immediate future. Some may recall the swine flu vaccine of 1976 which was discontinued due to the increased incidence of Guillain-Barre syndrome in many recipients. Establishing herd immunity by "medieval" methods (allowing mass infections with deaths of middle-aged and elderly individuals, persistent or permanent post-infection sequelae in many survivors, etc.) poses not only moral and ethical dilemmas to a society, but also decreases the work force and GDP. I'm sure that everyone has noticed the profound difference in the infection rate curves for the EU and the US. Europe suffered early, took appropriate draconian measures, and is now re-opening carefully. The US, by contrast is now a pariah in the international community.
