That's because you still have the (engineer's) mindset that an equation must be there to get an answer.

For me - and for a lot of other people - the point of the equation is to focus the questions ie to indicate what are the variables that might be more significant than others, and where can uncertainty be reduced most effectively. That is really a different approach to the DE.
The significance of the factors relies heavily on the formulation of the equation. What if the relationships between the parameters is different to how they are modeled by the DE?
