Media outside Sweden seems to get it wrong after what I have seen. It has nothing to do with intentional herd immunity - even if it's the only thing that will stop the virus (it will not just disappear) besides vaccine, in a couple of years. The strategy is to protect the elderly and risk groups and avoid seeing other people than your closest family. So I don't go to see my parents, who are in self isolation at their country house, but there is no law that keep me from seeing them. Outside my window I can see a woman on the street talking to her mother who's on the balcony on the 2nd floor. It's all about keeping distance. It's a strategy that could last for years, while a total lockdown is possible to do for some weeks. Sooner or later every country has to loosen up restrictions, which is happening in many european countries at the moment and that will most likely cause a second wave. So it's building on lots of information and responsibility.
It's mostly open here, though they are closing down restaurants immediately if they don't follow the rules, high schools and universities are closed, etc. Stores are open, but there are very few people, so businesses are breaking down everywhere here as well. It means you can still play badminton, but there will be a few people on the courts.
