I don't really disagree with anything you said, though not sure what you meant by "just making the 'perfect' character build".
First, I enjoy making new powers/stunts/templates/whatever, its my favorite thing after "the obvious" and programming. Creating new stuff helps give me a better grasp on the system and, as in this case, helps my players better understand what they can reasonably do or expect.
I understand the concept of rp and character story being the most important. I've GMed for power gamers who only care about rules and rolls. I've also GMed for free-formers that don't understand using anything other then their mouths and note paper for rp. My favorite aspect of the Fate system is how it blends the two worlds together so well.
This power is a bridge between the two. Not as broad as Psycomancy or Supernatural Sense (Telepathy), which would make the stat players itchy and worried their powers aren't worth as much. At the same time it is pretty open, allowing upgrades and simple mechanics so as not to frighten my free-form players. Add to that the remove of worry for the metaphysical side of Lawbreaker, but still getting to fret over fanatic wardens not care how you "broke the Law".. that got both groups pretty excited, even the players not taking the power.
But like you said, "There are multiple ways to achieve the same desired end, all without taking the same path." This is just another path I am providing my players. Those that don't wish to take that path are by no means forced to.
