Yeah, it's like you said. Smart people get other people to help about the things they can't or don't want to deal with. If you are in a position to do that, it definitely keeps your focus on the main thing - music.
And the fact that if you are dedicated to creating your original music and playing it, things wont stand in place, at some point the whole business part starts happening on it's own even if you want it or not. If you're sure of your talent, work and craft, you wont spend your brain-space thinking how can a new business model enhance your art :)
