I'm sure some of the biggest names in music would disagree with you since they all use producers regularly...but you're free to have that opinion.
I've never worked with a producer on my music...but have done it for some other folks.
I would be blown away to have someone like T-Bone Burnett come produce for me. I don't think that artists like The Wallflowers, Alison Krauss, Robert Plant, and the late Roy Orbison called him up 'cuz they felt "lost and insecure".
But personal opinions aside...the reality is that if you are a nobody, and you get a record deal opportunity with some major lable...be prepared to have a producer in the studio with you.
They ain't going to drop serious recording cash on a newcomer unless he/she has a LOT to show going in and a proven track record of making the right studio decisions with pro/commercial product.
I just think it's always a great learning experience hearing a pro's opinion about something that you are working on...hearing about what they are hearing in your music.
I had a couple of opportunities in the past where someone wanted to play one or two of my tunes with their band....just local stuff...and it was very interesting and cool to hear their version. They came up with an alternative production that I never even considered.
That's all a producer does.
That said...not every producer is right for every/any artist, and there have been cases where the initial producer was fired/changed/etc because the production was going down the toilet....so just having a producer doesn't guarantee anything. Ideally, you want to first gel with the producer before you get going with the recording sessions.
