Without a comparison of other Nordic countries I find this whole analysis rather suspect. Just because the analysis is long and elaborate does not mean it is a good one.
It avoids the most obvious comparisons such as comparisons with Norway, Denmark, Finland and Iceland with significantly fewer deaths.
The analysis also entirely avoids an analysis of long COVID. It makes the classic mistake of equating COVID19 with the flu when the latter does not affect multiple organs in the complex ways COVID19 does leading to long term health problems for a large number of people infected who survived COVID. The flu has no such comparable effect.
It also completely ignores that Sweden did engage in social distancing and took many active measures. Thus it was not treated like the flu at all. Public transport, restaurant visits, number of people in the office was significantly reduced. Thus there are too many missing parts to this analysis.
But as usual I suspect this will get voted into the stratosphere by deniers who latch onto anything opposing the mainstream narrative.
