Jennifer's commentary made me think that the corporate/new-org dichotomy may actually be, like most things, a continuum. One of Henry Ford's innovations was the assembly line, but another was hyper-specialization, the time-and-motion attempt to expel variation from the system.

Then, too, as an entrepreneur you need a certain margin for error. You need to be able to survive accepting the wrong client, or turning down a client, and as a sole practitioner you can only do that so many times. A larger organization tends to have a little more ability to guess wrong, at least in the sort term.

Not to say the one is better than the other; this is just musing.
