Can We Have Your Liver?

It's a step, I suppose:

Tomorrow, the California State Senate's health committee will review a bill that, if passed, will make California the first state in the nation to create a live donor registry for kidney transplants. The bill will also require California drivers to decide whether they want to be organ donors when they renew their drivers' licenses.

According to one notable supporter, this second measure alone should double the number of organ transplants available in California.

How about instead of requiring people to do things, we allow them to do things -- like trade freely, even organs?
