I would do it, but they'd have to lift the law regarding weapons of mass erection destruction.
Ahem, now that that joke's out of the way, no, I don't think that I would. I'm in decent shape, and I'm not absolutely horrible to look at, but I like my pants and shirts, and all the other clothes. I might walk around with no shoes, but that can get uncomfortable with the stuff that's on the ground, and the temperature of whatever surface you're walking on. However, if you're in public, you have no expectation of privacy, so I'd probably be carrying around a camera. XD
Oh, and I love my pockets. They hold things, which is useful.
