It is not uncommon in European culture room to have mixed public saunas where people are naked. Human bodies are regarded as natural and there is nothing erotic or humiliating in such situation. Everyone minds their own business. Also when I browse the web or I walk on the street, I am visible. If I enter the shop or web page, the owner of it will take a notice. I think it is all natural. The situation changes when an interested third party appears who shows up keen interests about my doings. Follows me every corner, marks down at what I look, or what I buy, even follows me into public sauna with an intent to take pictures of me when I am naked and all of this with a sole interest to take advantage of me in every way possible. This is not natural, this is perverse. This is where a normal person says: leave me alone, please respect my privacy.
