It seems to me the only conclusion we can draw by studying Sweden is that Sweden's policy may have worked for their country for the studied timeline. Let's see if it continues to work going forward. We can't say for sure that the policy was what kept virus propagation under control, it might just be the set of factors outside of the government policy. Similarly we can't just apply the same policy elsewhere, in completely different circumstances, and expect for it to yield similar results. Policy has to be decided based on as much data as you can gather, find out the main virus propagation causes and try to deal with those in an effective way. Don't do something because "Sweden did it".
