Gene Roddenberry planned to depict widespread public nudity amongst the civilian population of 23rd century San Francisco in order to visually indicate the era's "mature attitudes" concerning such matters until Paramount's Michael Eisner demanded a G-rating for the film.
Do you really believe it was that and not simply more of Roddenberry's teenage male approach to sex through which he tried to shoehorn as much cheap romance novel crap into Trek as he could? I suspect the latter. And running around naked would demonstrate a more mature society? Clothing has a wide range of utilitarian functions beyond simple modesty and I doubt it's going away no matter how "mature" our society becomes about sex. No, I think Roddenberry just wanted to be able somehow work naked women into Trek.
