So instead of comparing a country with other countries of similar demographics and culture [including tendency of extended family to live together and habits of social distancing] you would rather compare them with countries that would be more prone normally to the spread of disease. Instead of comparing to countries where less than 2m is considered pushy, yeah lets compare them to countries where not licking each other's faces is considered standoffish.
Also Sweden would be about as empty if not more so than Denmark, Norway and Sweden if you look at cities. and towns. That large parts of Sweden, Norway and Finland but not Denmark are empty forests not only makes little difference as those regions don't have many people but actually lends to the point that you need to be careful comparing country to country.
