I would think that the idea arises as a result of the need/desire and not the other way around. I couldn't agree more with the idea that value is the result of many factors including the idea, the plan, the team, the environment. Claiming that value is a result of X makes for an interesting claim/discussion, but in my experience, is hardly ever true. Value is the result of many, many different factors, including all those that you listed (need/desire, knowledge of the market, a plan for execution, resources, timing, etc). Nothing is as simple as we try to make it.
