At least from my point of view in writing the article, strong -> power to move; stubborn -> refusing to move. I don't think anyone should be die-hard anything, because there's always a lot of grey area, and, as you said, you can rarely work in such an ideal environment. But having an idea of the tradeoffs you're making is extremely useful.
