I think the sticking point comes when we try to define the rights of one stakeholder vis-à-vis the others, because they really are (or can be) competitive rights. We see this regularly when one group promotes the absolute right of the fetus and another group promotes the absolute right of the woman (or privacy, etc.). My guess is that each stakeholder group will appeal to the "science" they think will support their respective positions and claim that their rights are absolute.

As a physicist, I would be comfortable working with a mathematical model similar to the Nash equilibrium, but I think most folks would want to approach the subject from different perspectives.
