Isn’t the only reason the speed of causality is the speed of light because light is the fastest thing? And if you were able to go faster than it, that new speed

  There is an interesting property of the speed of causality, that it is fixed independently of the observer (as in, any observer will measure the same speed). Our mechanics allow only one such speed, and if you try to use one that doesn't have this property for causality, you'll get all kinds of paradoxes. But it's probably something that can be solved. All said, the reason we assume causality moves at that speed is because it agrees with the experiments.
