I'm guessing a lot of paying gigs are not in your future, then.
If you want to get things done, you need someone in charge. If you want to hang out and noodle around with ideas, the all-collaborative approach is fine. The best musicians I've played with (and some of them have been pretty spectacular) were perfectly happy to come in, sit down, and play the music the way the leader wanted it, get paid, and go home. Although at my level I can't say like one of my mentors "the instrument doesn't come out of the case till I see money", I appreciate the attitude.
News flash: 99.999% of the music you love, of whatever genre, was created by an organization with a "band leader" and "side men". And in most cases it was recorded by studio cats whose livelihood depended on coming in, sitting down, playing the parts, getting paid, and going home. You don't really think that all those complex licks and bass lines and song forms and arrangements were arrived at by consensus amongst all the band members, do you? Nope, one guy said "here's how it goes" and the others learned their parts.
