No, we've had pandemics before, we've studied outcomes, and lockdowns aren't exactly free, but they generally reduce deaths. There weren't 100k deaths "caused by the lockdown". Furthermore, there's lots of non-lockdown things, like social distancing and mask wearing, that would have helped hugely, but weren't done.
Mostly, though... If you want to claim that there's extra deaths from lockdowns, don't offer speculative narratives and how you feel like lockdowns might lead to deaths. Offer real, solid, numbers. Epidemiologists have been writing about the direct and indirect effects of policies like this for over a century. We have studies and graphs from the 1918 pandemic, after all. So on one side, we have basically all the science that's been done in this field, regardless of political affiliations or country, for more than a century, and on the other hand, we have a small population of people, more than 95% of whom are right-wing, who are making claims contrary to that science and who offer no actual evidence, just speculations and vague handwaving appeals to "extra orphans from the lockdowns" without actually justifying or supporting the claim that the lockdowns kill people.
Also, no, covid's mortality rate isn't really "more in-line with the common flu". I know that was a popular thing to say early on, but it's stupid. Yes, it looks low if you disregard all the people who have other health problems, or who are old, and so on... But you know what? If you want to do that, you have to also look only at flu death rates excluding all the people who have other health problems, or who are old... And then you run into the problem that it's really hard to measure that death rate because it's so low. (I've never actually personally had anyone tell me about someone they know dying from "flu" who wasn't old and unhealthy to begin with. I've long since lost count of the number of people I know who know someone who died from covid, and not all the dead people were old or unhealthy.)
