In Europe seatbelts are mandatory, and it is forbidden to smoke in most places. I think that these are reasonable measures. I think, for the exact same reasons, that mask mandates are reasonable.
In public transport is mandatory to wear at least a t-shirt, as skin to skin contact gets unhealthy fast. And restaurants require to clean your hands after going to the toilet.
What does not fit with my idea about the USA is that you can go naked in the street, as it seems quite a Puritan country. And books being censured in schools for mildly nudeness also seem to be the norm. Is not that worse that mask mandates?
Edit: seatbelt
