I agree with you on that.
Short, directed lockdowns at infected areas (talking of 3 weeks) works, but keeping a lockdown forever isn't effective.
it's not the flu but its not the bubonic plague either
I have felt from about mid-March to early April 2020 that was the case.
We should have protected those who needed protecting, and let everyone else live their lives as they chose how best to protect themselves.
The total lockdown was asinine.
