Don't pull the "my body my choice" bs, because it doesn't apply when commerce is involved. You're free to cut out your own organs, you're not free to create a system of economic incentives for that process, because that's outside of your body and clearly in the realm of broader social impact. I know you know that the government regulates business.

This problem is solvable through social programs, and I made another post in this thread explaining how I think that might work.
