The transplant list works on a point based system. What if those who previously agreed to be organ donors get a bonus point on the list to reduce wait times?
What makes it worse? So far, you said that the things that make it bad are 1) it's removing a choice and 2) causing citizens to get "equivalently" murdered.
It's worse because it causes a significant net increase in suffering and death relative to allowing people to do what they want on their own.
I didn't actually say that removing a choice is inherently bad, although often it is. I was explaining why I was holding the government responsible for that action.
Removing the restriction would be equivalent to the government murdering large numbers of different citizens.
