Yeah, people can take things too far. There are definitely safe ways to go to a store, if the store is taking precautions. I'm not so sure about indoor restaurants right now in the US, but I guess you could make a case for it.
On the other hand, I can see why being gaslit for a few months would make lots of people neurotic. The sky was really falling for awhile before anybody in power in the US seemed willing to acknowledge it. Personally, I've lost a lot of faith in our public health departments to have the freedom to tell it like it is, or to have the budget to do anything about it. Being in New York City for the last few months probably doesn't help.
