Speaking as an artisan, you're wrong (as a general but not ultimate rule). We have a fundamentally different set of neural pathways, both in-built and learned and whitest anyone can design, leaps of artistic creation show a lack of the formulaic which is often apparent in lay-design.
Obvious exceptions are artisans who learn business and business people who master design to such an extent that it becomes indistinguishable from true art. The work and reputation of the former tends to become corrupted by their ulterior mode (see Norman Foster), the latter turn into Steve Jobs...
The third, and rarest exception is those who are intrinsically capable of both art and business, the most recent example I can draw to mind is Danny Boyle.
I don't know CC, but from the brief chat we've had, and the work that he (she? Gender unknown) produces I'd say they fall into the "I make what I make because that's what I do" category money is not a motivator but a boring necessity.
CCs caps could be made in mass quantities, but to my eye they're made using a far, far, far lower yield method (not posting my guess) than SP uses (vacuum injection with $$$$$ machines?). Further more, we get to see the number of seconds CC produces, but not the number of outright rejects - the cost of which must be covered. Oh I could go on, and on, and on. But I'm sure this'll already earn me another TL;DR...
