I am living in rural Sweden (originally from UK). I agree with you OP. Sweden most certainly did not carry on as usual. But other factors come into play.
Sweden is a population of 10 million. It has the largest proportion of single households in Europe. Over 50 per cent of Swedes live alone. Add to that an average of 25 people per square km in Sweden as opposed to 275 per square km in the UK - you are looking at a natural social distance.
Locally, all schools remained open but end of year shows and concerts were cancelled. The above poster said secondary schools closed but where I live only colleges closed. After school activities ie football/basket ball/rowing were shut down and remain so. (Having said that the Friday night youth centre reopened in August). Midsummer celebrations were cancelled. We didn't go ahead with with birthday or Halloween parties. Our local hair salon was closed due to the owner officially testing positive for Covid.
No masks are required but screens went up at the tills. Markers were placed on shop floors as 'distance' reminders and IKEA /fast food restaurants still operate colour coded distance seating.
Flights have been cancelled via the airlines - my local twice a week easyJet flight to London running from beginning of December to the end of April is only showing once a week flight from the end of March.
It was not business as usual. It was a huge social experiment - literally playing with people's lives.
