I avoid getting into Raw vs jpeg arguments when it comes to people deciding a personal workflow for general photography because it does depend on various things. The type of photography you do and your needs and preferences will factor in there and nobody can tell you what's right and what's wrong. I've seen/heard good reasons for people who shoot jpegs some/much/most/all of the time, and others who typically shoot Raw+jpeg to get the most out of both formats.
The biggest reasons for shooting jpeg are some combination of speed, convenience and space saving. If a person has the skills to "get the shot right" in the given conditions they are shooting in, these could certainly be very good considerations.
But, the fact is that there are fundamental advantages to the Raw format that won't just go away because of these considerations. True that you can be very happy with your jpegs and that you can even do a degree of post processing to your jpegs and you can go crazy with "artistic effects" with jpegs and so to you the advantages of Raw may not matter.
But, over and over again people come on the forum looking for ways to improve their photos -- not necessarily "fixing user error" (that's really a diversion
) but ways to enhance a photo in various ways, and one of the most common questions is "did you shoot this in Raw?". This is because so often we may want to look at, say, highlights and/or shadows, or fine tune the colors or whatever and the fact is that you have significantly more latitude to do that with a Raw file. Fact. True, you can do some with a jpeg. True, you can make a bit of an adjustment to the White Balance with a jpeg -- just don't do too much or things can get ugly

I went totally Raw some time ago because, for the type of photography I've done over the years, it made sense that I would want the full range of processing capabilities possible. Sure, I used to shoot point & shoot cameras and compact digicams and have had plenty of jpegs I've been quite happy with, but I also occasionally would want to work over an image and found the limitations frustrating. Also, I'm not a studio photographer or typically one who shoots with controlled indoor lighting where I can just set up and shoot -- I'm usually outdoors dealing with a variety of conditions, a lot of bright daylight highlights and darker shadows and such, and these are conditions where Raw files/processing will outshine a jpeg, well, any day
