That's a good question. When Steve came back to Apple through the NeXT acquisition, he didn't come alone. He brought a team of smart devs, and a pretty awesome technology stack (Foundation, AppKit, Objective C).

Now Steve was obviously the lynchpin and you probably couldn't have gotten one without the other, but I wonder hypothetically what the value of those things separated would have been. Steve alone, or team+ip alone. I suspect neither one would have been as valuable as both together.
