>1. If people were that afraid they would have been sheltering in place before the government ordered them to do so, but they were not doing that, and they only started doing that when the government ordered them to.
People don't tend to fear something until it's tangible to them. When one of their family members or best friends gets ripped apart and then dumped into a grave, it will become a lot clearer very fast what kind of danger it can pose to oneself.
>2. The behavior of people after the lockdowns ended.
Some people are behaving that way, but I'm pretty sure it's mostly limited to America where we've decided wearing a mask is a political statement. (There are exceptions, but they are also often other places with similar or worse anti-science/medicine sentiment.) It's hard to even know what the outbreak would look like if both businesses and all ordinary people went back to normal. I know the economies have not recovered anywhere where lockdown has ended.
