There's a lot of criticism of places that kept schools closed for longer than was necessary, in retrospect. But we really didn't know whether it would always be the case that the risks to children were low. The virus could have mutated in a way that brought more risk. Or there could have been chronic effects that could only be seen after the passage of time. Given the infectiousness of the virus, it could have been so much worse.
I get the vaccine hesitancy. But I think a lot of people were not willing to accept that vaccination is not just about their own safety, but a collective safety issue.
And the next time this happens (which it probably will given the statistics), the US will probably handle it much better and the lock down will be less severe. I'm Korean American, and something like 10 years before covid, Korea had gone through an earlier pandemic (swine flu?), so when covid hit, it wasn't that big a deal. They already all knew what to do and the lock down wasn't as severe.
Yeah, our lockdown was overkill in many instances, but it was all so new to us. There's a good chance it'll be a lot better managed the next time.
So public policy should have reflected that, instead of going into counterproductive authoritarian clampdown mode. In my country the authorities literally switched overnight from threatening to jail parents who took their kids out of school to announcing mandatory school closures.

So yeah, I do see your point in the lockdowns were probably unnecessary, but as others have mentioned, pandemics were new to the US at the time, and we didn't have the knowledge and procedures on how to best deal with it. Yeah, we did probably go overboard, but what happened is understandable given how deadly Covid was.
We know now that social distancing and masks (for those that are willing) would probably have been enough, as other countries used to pandemics already know, like South Korea.
