Why not rather instability?
Consider … if an object is uber-stable and at rest, it is boring. No motivation to move, advance or do anything. Whereas instability means:
Move, change, advancement forwards.
Why desire stability?
It seems individuals who desire stability are just fearful. Fearful of the future. Fearful of the unknown.
It also seems that in order to plan, one needs people who are stable, reliable and dependable. This is how modern society works.
But let us say that you’re random, unpredictable — like a wild beast. Nobody can control you or know what your next step is. In this case, you are of no utility to society. You cannot really “help” anybody.
