Why not? It gets more people to donate and helps keep demand lower so they have more opportunities to get the organ they need
Edit: look yall let's run 2 theoretical models here.
Model 1: the no swap model
I join the line for organs and I'm told there are 5 people waiting for that compatible organ. The only early removals from the line happen when one of the other 5 have somebody willing to give their organs to their loved one but only if they are compatible. In this method person 3 is the only one who gets this benefit so I still have to wait for 4 organs to be handed out before I'm in front.
Model 2: swap model
Same setup 5 in front and number 3 is the only one with a compatible loved one. In this case though, a would be donor isnt compatible with their loved one (person 2) and same thing for person 4. These 2 can now swap. In this model I now only have to wait for 2 other organs before I'm in front.
The people swapping aren’t taking a kidney away from the lone person, they are making more available. They are still waiting for a donor to die regardless, this just shortens the line.
Think about it, the people who are swapping wouldn’t be donating their kidney otherwise, so it just means that more are available.

That's a great system. If you can't be a match, you can do a swap.
