You're getting downvoted because you provided zero evidence to backup a claim that seems pretty absurd. Touching your mask to adjust it is not the same as touching your nose, mouth, or eyes directly. Pretty much every reputable recommendation says to wash your hands after removing your mask, which avoids the contamination problem pretty well.

And to your point on Scandinavian countries, where are you getting that information? Here's Norway mandating that travelers from "red" countries wear a face mask until they get home [1] and planning to backpedal on their lax mask policies [2]. Here's Denmark backpedalling on their original mask policy [3]. Here's Iceland updating their policy because they also realized no face masks is a bad idea [4]. Basically, Scandinavian countries now recognize that their original policies were not that great.
