Earlier quoted context omitted.
I think you're inventing a past that didn't exist. Were this pandemic to strike in the 70s or 80s (or earlier), we would undoubtedly have given people little choice to be vaccinated, but we also probably wouldn't have forced people nearly as much. Today we are stuck with these people running around talking about their freedom, when one of the main reasons for government is public health.
I think if this pandemic struck in the 70s or 80s, it would have been shook off as a moderately more dangerous version of the flu, and there would have been no lockdowns or anything like that. Life would go on as normal until natural herd immunity is achieved.
You would have ended up with full hospitals everywhere and people dying in the streets, and the Delta variant way before a vaccine was ready if we didn't do lockdowns.
