The idea of adjusting your guitar until happy works fine much of the time.
But what if you are setting up a guitar and desire [b]a lower string height than the build quality of the guitar will allow [/b]? or you are setting up an instrument for someone else and they require a lower height than the instrument in it's current state will allow ? or the instrument's owner requires a certain spec ?
This is the kind of situation that may be presented to the luthier.

Then it will not work or sound good. You would, by it's very nature, have to do more work to attain the string height.
Feel is better than measuremnt on an organic device like a wooden neck.
I understand what you are trying to say and achieve, but I really don't think it works in reality
