It is interesting to have a case study such as Sweden. As they themeselves are syaing, nobody knows yet whether this strategy is the best one in the long term. Looking at deaths now you could easily say no, but you have to factor in other things such as mental health and economy - as mentioned in the article.
The only issue with the economy argument is that most other countries have locked down, which will always have an effect on Sweden economically regardless of thier approach.
The fact that Nowray and Finland are open to eachother but closed to Sweden is quite funny but sad at the same time.
Only time will tell.
I don't think Sweden's response is that different to the rest. Their experience can definitely not be used as the "do nothing" baseline.
They had a lockdown, but it was more voluntary where their neighbour's lockdown was more enforced.
