While I'm a proponent of voluntary euthanasia under some conditions I think this post is overly dismissive of why people might shy away from it.

Also on the note of rhetoric:

If you want to promote the position it's probably best to not jump straight into taboo tradeoffs.

Framing it as a way of boosting organ donation rates will cause people to have the same visceral reaction that they would to saying that baby-torture would boost company profits.

Terry Pratchett's Richard Dimbleby lecture Shaking Hands With Death handles it pretty well as it frames it as not wanting to spend the end of your life with tubes trailing out of you which is more along the lines of trading sacred value for sacred value.
