This isn't a smartphone that I project into the world, it's just the conclusion of what I've seen and my logic. You may think it's wrong, but in my eyes it's pretty clear, when we strip the problem down to the core:
Some people are born with the power to bend, others are not. While the latter may envy the benders there is a of now no way to replicate the powers. They can't bend and they know it. On the other hand, people with bending powers discover in their youth that they have it and it's part of their life. They may invest time into learning how to use them, they know its part of them and for all they know, its something they keep until they die. It's a part of their normal body functions. And suddenly, one day, someone take it away. Although they know that there are people who lived all their lives without bending, they have something take from them what is theirs and only theirs.
It's like you're born with wings, used to soar through the skies and someday someone cut them off. You know a lot of people who have no wings, who live perfectly fine without them. But you know how it was to be above the clouds, to chase birds, to see the world from a viewpoint your fellow people couldn't see.
I think its better if we stay in general and not go into the details of an example.
