I don't exactly know what you mean by "confrontational nudity." We all know that confrontation can backfire on us as a strategy. Perhaps you could explain that.
Taking the risk of being seen depends upon who and where you encounter. You are unlikely to meet someone on a trail that objects. When you increase the population around you, you would, by the odds, increase the likelihood of encountering the vocal odd fool that might object. That is numbers.
There is a certain sense of ownership and belonging inherent with more urban situations and psychologist that also may contribute to someone more likely to object. Some people generally dislike anything that seems out of place to them. These people don't do a very good job of questioning or intellectual processing. They do a lot of assuming and accepting social mores and habits.
So, depending on what you actually mean by the phrase, I probably could disagree and show you some numbers why. Whatever you are saying, you aren't supporting your statement. I suspect that you have no supportive evidence and are just calling something fact that you pulled out of an assumption hat. There are plenty of myths about nudity among the textile obsessionists.
"All the same, there are probably still some good beaches to visit where you won't disturb anyone if you're willing to go the (literally) extra distance." There is an assumption of disturbing someone. Let alone that one is justifiably disturbed and not just a jerk, most people on a more remote beach location will not be alarmed, as is the story on a trail. If you do it on Miami beach, with all of those people, some one will not like it. Most don't care much, or they approve. I've got statistics for that one, which are somewhere in this forum.
Blue train, how is it that you are disturbed by someone enjoying anything nude? How is anyone disturbed by anyone being nude? Why would you would assume this?
There are very powerful binoculars. But then somebody has to use them for a purpose. If you are alone minding your own business on a beach nude, in most places you are disturbing no one, alarming no one and breaking no laws. That's what a beach patrol will see with those binoculars. No intent whatsoever. You are presenting, again, typical textile fear mongering as fact. Why do you spread fear mongering crap. Unreality. Is it that you want to discourage naturism, free range naturism and progress?
It is curious that Playboy of old had anything to do with this beach thing. It just associated the free beach, naturist population with the sexual objectification playboy mentality. Playboy got thrown under the counter away from the kids as some kind of adult entertainment by the same people who it confronts. With associations like playboy, these same influences will kill any nude beach as another nasty thing. Playboy was not a good place to promote a nude beach, but a good place to discuss body freedom and a good place to confront Playboy for its antiquated shortcomings. If that was the case. Playboy was a step into change that needed to happen at that time. Things are evolving socially from that point when Playboy made significant difference.
