To me, raw simply gives me flexibility.
It gives me flexibility to explore the recorded images more fully in post-production, without any loss of fidelity. It gives me the chance to do what-if type exploration, and often when I do, I discover that my understanding of how the camera behaves is off a little, and that I settle on as most desirable is better developed in post than off the camera directly. Yes, if I'm in a rush, I will often take jpegs right off the camera, and share them. But then I will run through a post-processing workflow, prioritizing a handful that I'd like to explore, and then running through exposure, highlight/shadow manipulation, pushing my levels, getting creative with color balance, etc.
And doing so gives me a better understanding of how my camera behaves.
