There's a lot of talk about the... um... mechanics of the acts involved. As a libertarian, I respect the right of people to do dangerous, immoral, and destructive things to themselves. It's your life; who am I to tell you not to ruin it? And since I don't want you poking your nose into my affairs, I ought to afford you the same courtesy.
However, I'm torn on the larger issue at hand: Should the US Supreme Court be telling the states how to run their affairs? On the one hand, I like the reservation of powers and rights embodied in the 9th and 10th Amendments. Governance in the US was intended to be from the bottom up; not the top down. On the other hand, I don't want things like gun laws written by the loons in Sacramento. In that case, I'd like nothing more than to see SCOTUS use the 14th Amendment to ram the 2nd down their throats.
