Art Caplan and George Annas are bioethicists who have recently spoken on this topic. Ben Hippert is a nephrologist who has weighed in as well. I'm an amateur ethicist, and not a medical professional of any kind, but I've represented living donors formally and informally in public forums, to various committees and conferences of the OPTN and UNOS, and here at LDO, often.
May I suggest you consider a different title? "What Conditions Might Allow Stakeholder Reconsideration of the Criminalization of Compensation to Living Organ Donors?" This defines the debate space respectfully for all, and includes incremental change, such as the recent legislation (Norwood) clarifying NOTA to allow Kidney Paired Donation. Best wishes for your research. If you're willing to link or post your essay, we'd enjoy seeing it.
