Nude beaches are pretty old as a concept? Always a niche community but there's definitely been hippies talking about non sexual nudism for decades and etc

It must have been non sexual at some point in our historical development, before clothes. So I can't really agree that it's inherently so - just that we've culturally made it a sexual thing for basically all of history. That might be close though to functionally be inherent to human society depending on your viewpoint though.
