I'm all for people going commando in appropriate places if they wish to. I would be worried, however, about the feelings of those who are not so minded, if nakedness was allowed anywhere and everywhere; without restriction.
I suppose it would be fine for those with beautiful/perfectly endowed bodies without ailment, age and/or blemish. What of those who grew up in times when such things were frowned upon? It is not that long ago when showing a little bit of ankle was taboo.
I don't think I'd be buying sausages for too long if Mr. Eight inches was freely swinging around the butcher's shop and carrots would be a 'no, no!'
Would nakedness continue into a British winter? That might shrink a few egos. Jack Frost would become public enemy number one!

It would then become a blue issue rather than green!
What about children and some of the insidious people within our society? I can understand that if we lived in a suitable climate where it had been the 'norm' for hundreds of years, nobody would bat an eyelid. But we don't.
The thing is, society - ergo, the general consensus of the populace - does recoil from general nudity for a lot of valid reasons. It does not force people to wear clothes in selected places, but it does have to protect those who choose not to comply with nudity. If it does not, it infringes the rights of those who do not agree. I for one, would not have felt comfortable taking my young daughters to a public beach where nudity was allowed. Everything in its own time and I hope I do not come across as a prude; I am far from it.
