Poppycock, I say! Moral theories are presented all the time, often haphazardly. There's a reason why, of course, it's probably the most directly practical and derived of the philosophical fields. Everyone except for sociopaths knows they need it and though usually not in a fully conscious from first principle up to individuated instance sort of way they formulate their own codes. Often it is simply what works practically.

The logical importance of judgment (and morality) is not merely elevated in the context of a species that possesses free will; it would be nonsense to pursue it otherwise. If we are determined by our very nature, moral examination is at best a vacuity - we can only do what we will end up doing, the problem of "ought" becomes very much like a divide-by-zero error. I couldn't oppose determinism more staunchly if I tried, myself. It's one of the metaphysical backbones of my libertarianism.
