In no way can acceleration be said to be a "more important" value than any of the others

HP: What a physicist means by a ?more important? observable is that it is more objective. 
That is, it enters universal laws of motion with the least dependence on the state 
(positions and motions, and even biases and opinions) of individual observers. Thus in 
physics, acceleration is more important than velocity because the universe obeys 
universal laws based on acceleration, and do not depend on the observer?s velocity. 

The idea that all perceptions and observables are equally important leads to no theory of 
anything.
