I haven't read this whole thread but here is my two cents.
I was a happy, active, basic open water diver for nearly 15 years. From there i went on to DM in a little over a year. Primarily because a group of friends were doing it to support a new dive store that another friend was starting up. Along the way i found out (quite by accident) how gratifying it could be to help other divers, new & old, enjoy the sport. So i went on to become an instructor as an extension of that.
Like every job, DM/Instructor has its ups and downs. The biggest downers in my mind are the potential liability issues and the rising costs just to keep teaching. And I would be lying if i said i never called a dive because i didn't want to be in the water with someone(s) who looked like an accident waiting to happen and would not listen to reason. However, i rarely thought that way before becoming a DM. So that knife can cut both ways.
The biggest upper is the satisfaction any teacher feels when they see their student "get it". Anyone who has ever taught anything, understands what I'm saying. It's hard to describe but it is a great feeling.
So to answer the original question, i ask students, who i feel have the experience and temperament needed for the job, to consider going on to DM so they might experience that same feeling and pass it on to improve the sport. It sure as heck isn't because I'm looking for tank monkeys. I haven't met a DMC yet who could out "tank monkey" me. They will however be expected to carry more than their own weight just like i expect from myself. IMO, that is a basic part of being a good DM/Instructor.
Not every Instructor has nefarious reasons for asking the question. In fact, in my experience, it's quite the opposite.
