Thanks for pointing this out. That hypothetical was a strawman -- Victoria's Secret is never going to run with a photograph without a model release form, and they may actually fall under the pornography regulations that require age confirmation as well (I'm not sure about that one.)
... and it's not like such companies are lacking for professional models, or budget to hire them.
