CMV: Only those who previously registered to be an organ donor should be entitled to receive an organ transplant when/if needed.

Most countries have a chronic supply issue in the area of organ donation. Over 8,000 Americans die each year because they can’t receive the life-saving organ they require. 

In the USA, only 45% of American adults are registered organ donors. Organ donation is, in theory, supported by nearly 90% of the general public. Why the disparity?

To fix this, I think a quid pro quo is in order:

When you register for your driver license, you decide whether or not you want to be an organ donor. Same process we follow today. You can change your mind later, just as you can now. 

However, if you receive a diagnosis later that requires an organ donation, your eligibility for that donation depends on your own status as an organ donor. If you are registered as a donor, you’re placed on the waiting list. If you’re not on the donor registry, then you’re not eligible to receive a transplant. 

A system like this will create more equitable outcomes, and no doubt will lead to higher rates of registration. Everybody wins.

Finally, there will be a caveat for those who wish to be a donor but due to health reasons are unable to register (have a disease, etc).

EDIT: children who were not yet old enough to register would not face less preferential treatment in their ranking status (in other words, this would apply >18 years or whatever).

EDIT: registration need not be predicated on registering at the time of driver license renewal. It’s clear there needs to be an easier way to sign up. Perhaps you could do so at the grocery store, or online, or at work or school. There would be plenty of opportunities to register, if desired.

We will just ignore all the ethical problems with this idea. 

This fails immediately for anyone who has read the Constitution. Some religions prevent the removal of organs. So, any law that prevents transplants to those who aren’t registered donors discriminates against some on the basis of religion. 1A violation, law gets tossed, we all move on.
