We're living in complex societies where reckless behaviour puts others at risk. If you live on a sheep farm in the appalachians do with your lungs what you want, the reality of modern urban society is that we're interconnected. In that context freedom and safety are mutually dependent, even reinforcing.
The idea of "I can do with my X whatever I want" and then stop thinking there and calling everyone a fascist or an oligarch made a lot of sense if you're a 18th century homesteader, it doesn't make much sense today.
Passing COVID-19 or flu onto another person, especially elderly, may kill that person. Walking naked with mask if you keep your body clean as far as I can see will not kill anybody. So, why should we enforce clothes if we do not enforce masks?
Also, children are perfectly able to handle asexual nudity. A lot of countries in Europe allow being top-less in public places like beaches.
There is just no way to justify things like enforcing bras on women, but not enforcing masks in crowded places during pandemic.
Freedom and safety may not be polar opposites, but there's certainly tension between them. Many believe that you should have the freedom to decide what to do with your own lungs. The idea that you lose freedom because your lungs don't work seems to be a willful misinterpretation of the idea of freedom from government.
