Can you estimate a percentage? Even if say 50% of deaths were due to lockdowns, do you really think that free movement would have not contributed to an equal or greater increase?

As a further counterpoint, I'll use Norway and Sweden as examples. Sweden did not implement a lockdown, yet had a 10x worse per capita death count than Norway. If anything, this suggests that you'd need around 70-90% of the excess deaths to be attributed to something other than COVID, which feels like a heavy bar to clear.
