So sorry Bonkers 
Safeguarding, for those who support it, doesn’t come from puritanical or paranoid feelings or silliness of any kind but from absolute necessity and statistical fact/experience/likelihood of risk.
We all need to practice safeguarding with our kids to protect them as best we can but also to help them develop appropriate boundaries to help them understand the importance of safeguarding. The risks are still applicable whether we want to see the world as being like that, or not.
I am very keen for kids and adults to be able to be around a range of different bodies (of their own sex) and this is all still possible to observe at a beach etc without requiring any nudity. I am also fine with a single sex expected-naked environment, with options for anyone who didn’t want to be naked; like a sauna situation. But I would never be happy in a mixed-sex naked environment as i would find it too threatening and oppressive, even if it was In a community where I knew everyone and didn’t feel literally vulnerable to attack. And that especially goes for a situation where I was responsible for children.
My issues about naturism as a political belief or movement are that it seems to arise from a very (what I imagine to be) specifically male experience/relationship of your own body to the environment, and to other people‘s reactions to your (male) body in society.
I do get the principle of wanting to take pleasure in being in your own body without fear of threat or shame or threat of your nakedness being sexualised by another person in any way that would fundamentally bother you. But in my experience this is a form of male privilege, or something that women talk about experiencing only when they are well away from the male gaze.
(This is one of the reasons why women object to the loss of single-sex spaces, like female-only opportunities to exercise and socialise- which is currently being done to us wholesale to pander to genderist politics, led by people who are happy to see safeguarding dismantled completely.)
Ster I’d imagine that many naturists have thought carefully about bodies and consent and context and the sexual differences between men and women and how that relates to power relationships and individual autonomy, as these are the fundamentals presumably of it all working as positively as some people feel that it does.
So for example, what happens when women have a period in naturist culture? How is it dealt with practically and regarded? What limitations (if any) does menstruation place on the full participation of women and girls in naturism? And also can I ask what is an acceptable level of personal physical privacy in naturism, before this becomes not-naturism?
