The word "you" is still 3 letters long.

Then you die. How do you benefit from that?

So, in essence, if you go back in time, "you" die and someone who looks just like you takes your place, n'est-ce pas? That's not really the point of this exercise, though. The point is to prove me wrong and come up with a way that you can use time travel for your own benefit without the necessity of living in a world where the Uncertainty Principle (nor any other law of physics, such as the Second Law of Thermodynamics) does not exist.
