This could be a good idea for airline (and heck, why not all modes of transportation) security. Fly naked. No shoes to light up, no place to hide weapons, etc. For the prudes among the pax and crew maybe spandex pants and tops, bare feet. no place to hide anything. Mind you on 85% of the population it wouldn't be pretty but it would make the security people's job easier.
Maybe the Powers that Be can require it....they seem to be able to require everything and anything else.
