With Unbreakable Vows, the... arbitrator?... sacrifices a portion of their magic permanently yes? One issue is that, after you die you might need that magic for something, like the more magic you have the more pleasant (or less!) magically created heaven is. In any case, even if magical society was fine with sacrifices, they might reason thus, and not use unbreakable vows. Such a society would make investigation (magical!) into potential afterlife a top priority, so lack of use of such a ritual might be compensated by finding out there is a heaven (or hell).
This is a society that has no problem using dementors as prison guards. I'm sure they would be willing to compel each criminal to act as the binder for one other criminal. It seems like a very small price to pay.
The next discussion thread is here.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 85. The previous thread has long passed 500 comments. Comment in the 15th thread until you read chapter 85.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
