The real lesson is that your DNA was never a secret at all. Almost the entirety of it is shared with many people (your family) and you literally leave it everywhere you go. Don't assume any of it will be kept hidden.

That's exactly why we need laws restricting what can be done with it without our consent.

That's not gonna happen. "You have to get the consent of your family members before you can share your DNA" is totally nonviable.

That's not what I said. The laws I am referring to would restrict the people with whom you share your DNA (23 and me, for example).

That's one logical way to with that, and (IMAO) the exact wrong way.
