Swedish, from Sweden here (de-lurking).
I’m not going to debate this, only clear up some misconceptions.
It has not been an “experiment,” at least in the way I understand the word, i.e. “Let’s try this and see if it works.”
In fact, it’s been the only viable way, according to our constitution (“Grundlag”): The state, as in parliament, government and authorities, cannot, repeat, cannot impose any kind of curfew*, mandate masks or social distancing. They can make recommendations.
What can be done, is impose some restrictions, using other laws, e.g. freedom of assembly is guaranteed under the law, but in public spaces you’re going to need a permit prior to things like picketing (this is to ensure traffic safety ASF, no one will be denied a permit for political reasons, as we’ve seen with neo-nazis for many years). So protest marches and picketing has been denied out of health concerns, which haven’t stopped anti-vaxxers or people protesting social distancing.
Local authorities (Counties, municipalities) have some measures that can be applied, but since these are ultimately ruled by local politicians, from across the political spectrum, depending on location, these restrictions can vary very much.
