I'm not saying I like this current system either, I but I could definitely see some downsides to letting people legally sell bodies for profit. It certainly seems chilling to me that people could have serious conversation about "what to do with grandma" if you have to consider not only how much it costs to take care of her, but also how much you could stand to be paid for her. It opens up a lot of unpleasant doors, but I guess its up for debate whether anyone thinks that's worse that what we have.
