I agree with what I think is the implied premise of your question - which - I'd make explicit as - its not clear we can agree what the lessons even were?

For example, was it good that we closed parks? Remember when sand was poured into skateparks? Or the parks in NYC were padlocked? Was it good that we closed schools for so long? Remember the amount of shaming that happened when some people went to the beaches? Remember when the grocery stores had arrows about which way the direction of the aisle went? Remember how long we handed out bacteria wipes as though it was spread through dirty surfaces?

I'm not sure us peons in society are the only ones who need to learn lessons here.
