The UK has ~2x the per-capita covid-19 mortality of Sweden, should English authorities be terrified that they've gotten their assumptions wrong?
You are cherry-picking like crazy!
There is clearly no evidence that stricter measures have any effect. If that was true, then there should at least be a linear correlation between strictness of measures vs. excess deaths, and that's simply not the case. You're extrapolating a linear correlation using a couple of data-points that happen to support your theory, i.e. Sweden vs other Nordic countries. Sweden vs. all of Europe paints a completely different picture, so you're not looking at that, because you're cherry-picking.
There are so many uncertainties around this whole situation, and I think the only thing we can say with certainty is that if a country has no or a low rate of excess deaths, that country is doing "ok". Not doing great, not doing shit, just doing ok.
