The jpeg format has advantages that add up to convenience from the smaller file size and a bit less processing, and, if you need high-speed performance when shooting, say, sports, well yeah.
And yeah, there are types of photography when shooting Raw won't benefit you much if any.
When it matters, though...when you have a photo or a shoot and you say "I really want to enhance this photo/these photos to bring out the best from it/them", then all of a sudden the advantages of Raw can matter, and sometimes jpegs just won't "cut it".
For me, when I go out to "practice photography" I want to make the fullest use of my cameras and the light and color I'm capturing, so I shoot Raw all the time. I don't have a problem, though, if someone hands me a P&S camera to take a jpeg snapshot -- sure, why not? But when I bring out my camera, I don't bother to stop and say "Hmm, should I switch to jpegs and just take snapshots?"...sure, I could do that, and just say the photos don't mean that much to me, but that's just not my style and mindset. Even in casual settings, I'd love to get some shots that could be processed, printed and such, and I don't think "They don't really matter to me"!
