I'm sort of glad the OP picked this up, despite disagreeing with them.
I've found this thread interesting reading in hindsight and with the knowledge we now have.
One thing really stood out to me at the time I think is reflected in the OP's position is the fact that we were "sold" the premise that lockdown was something we experienced collectively and was a equitable social burden.
Yet it was very, very clear that there was no universal experience and the lockdown rules had a very disproportionate impact on some families whilst being little more than an inconvenience to others.
My local FB page was riddled with the sentiment of "we are all in it together" whilst posting comments such as "I won't name and shame but to the family of 5 living near x street with the 3 pink children's bikes, you spent 2 rather than 1 hour out of your property today. I know it's hard but if I can follow the rules so can you".
Not naming, but giving enough info to make that family identifiable whilst showing zero self awareness that after they had done their hours walk, their family went to play in their huge garden, in the massive above ground pool they'd bought due to savings from Dad not having to commute to his safe job. Mum was in a good place as a SAHM to home school the kids and wasn't tearing her hair out because they'd bought the kids individual laptops re: online lessons and the house was big enough for everyone to have their own workspace.
Unlike their neighbours of 5 whose Dad's business was on the verge of folding due to lockdown and were worrying about losing their small 2 bed home with a tiny yard, all on top of each other with kids using parents mobile phones to do lessons whilst Mum is trying to hold onto her job, working out of the kitchen on the only laptop in the house - and going to the park for a few hours was the only respite from the shit show their home life had become.
Same rules very different experiences but so many people - especially those who sailed through lockdown seems oblivious to, apart from when it came to policing other people.
I was lucky re: lockdown so I've no axe to grind but I was (and remain) shocked at how many people failed to understand how the universal rules created massive social and financial inequality and seemed to take great joy/pride in shaming people who bore the weight of those govt decisions and derided them when they questioned the cost some families were paying.
