The personalities that respond to "authority" the fear based, the ones who were taught to crave rules and structure, to guide them and think for them, are more often the ones which cause problems for body freedom, who complain because it is out of place, who shriek, "What about the kids."
Duane, I don't think that these people behave with the intellectual capacity that your suggested lack of authority solution would require. They need a father figure, to tell them that it is fact, safe, alright, or to be lead. Even with that, some of them will just hunker down even more in their position, like a cornered animal that doesn't understand that no one is going to harm them. Most other people would respond as you say, to the facts presented by "experts", understand and make the obvious choices and adjustments.
People switch to fear and their brains go on fritz. They are very suggestible and easy to target. Ask any modern politician. Look at the effectiveness of these outlandish election tactics. It is chock full of fear based manipulation and less of the truly pertinent issues, qualifications, or informed decisions. I'm hoping not to make a political discussion here, but to provide an example of the mentality that we have to deal with to crack the social mores and images that are sustaining this culture of body demonization and sexual confusion.
Speaking of sexual confusion, The trans person is often a lot about dress and cultural gender identification. If there were no clothes, then what would happen with that? I've got a trans friend. I have to remember to ask her what her take would be on that.
