> My DNA is not a secret. The traces that shed from my body are not my property. Anybody is welcome to capture these traces if they come into that person's possession, whether it's fallen strand of hair or a DNA profiling system in an airport.

Umm, yeah, that sounds totally reasonable to me. If I shed cells all over the earth, is every piece of matter that was ever part of me my property in perpetuity? Obviously not. When I excrete or shed or discard, the matter with which I have parted ways becomes in the public domain of nature and subject to whatever exercise the public creatures may desire, from consumption for nutrition to examination for insight.

Sure man, follow me around and grab traces of my DNA is you want. It's none of my business.
