Reading this does bring back this feeling we constantly had during covid, that "its all pointless": The many rules about staying at home when sick, after being, when someone else is sick in the household: All these always felt somewhat arbitrary here in Sweden, and you always knew that you the rules did not guarantee no tranmission, and on top of that there was always the ones without symptoms. Which made all the rigor seems to unneccesary. We abided almost 100% to any rule, but I heard of alot of people who did not.
In the end, I don't think it changed anything, tranmissions till happened and would have happened.
