If that's true, then lockdowns aren't a valid answer either.
And on the side of not having lockdowns you'll find things that are much worse than some assumed percentage loss of happiness: people dying in total isolation despite not being sick, people dying of medical care that was withheld because they were too afraid to go to the hospital, a generation whose growth was stunted by lack of education and simple lack of human contact (according to one study, babies during the pandemic had a 22% lower IQ than babies from other years [1]), etc. We have done incredible damage to ourselves.
At the beginning of the pandemic this was justified, since we didn't know if this was going to be a mild case of the sniffles or some kind of air-transmissible ebola. Once we knew it was much closer to the first than to the second, however, we should have adjusted our policies, and we never did. I'm terrified that in the coming months we might see a return to lockdowns, as cases will inevitably rise again, and our politicians know only one answer.
I know an elderly couple that literally hasn't left their house, nor received any visitors other than for things like grocery deliveries, since the beginning of the pandemic. Considering how terrified they now are of the outside world, they will live out their lives in a self-chosen prison cell. They are both fully vaccinated (doctor came to their house for it), but refuse to step outside. Is that life?
As another poster here put it so eloquently: life shouldn't be treated as nothing other than a transmission vector for the virus.
How would you feel about a government policy where people are killed two years before their estimated 'normal' date of death, in order to spare society the massive medical cost of the last few years of living? Evil, right?
How do you feel about a policy where those two years are also taken by the government, but in the middle of your life? Sure, we weren't actually killed; we were allowed to keep producing. The only thing that was taken from us were all the things that made life worth living...
