You only have to compare Sweden with Norway, Finland and Denmark to show lockdowns have reduced the number of deaths from Covid.
Death count from Covid in the UK, where we both live, would have been double without lockdowns. As people in the UK are mostly idiots, most like yourself dont take Covid seriously. And who would not have socially distanced on own accord.
Whether you think the lower death count from lockdowns is worth the economic (and other) costs paid is another question.
