It's a nice fantasy, but sadly not correct. Delivering an important share of the production value is valuable on the business side, that's true. But it's not the major factor. It's one of multiple bargaining chips. Knowing the right people is another. Building hype for the product is another. Being directly involved in the sales process is yet another. And there are multiple more.
An enterprise is more than what it produces and therefore an enterpreneur also needs to be more. Not more in the sense of "higher level" but more in the sense of multi-tasking. Scale out, not scale up.
And being mediocre in each area is actually quite okay if one therefore is able to understand which area is currently the most important. If you have an exceptional product but nobody buys it, the hype building part is very well the most important area at that time, as an example.
So yes, craftmanship is important. It will make you produce great things, and the production of these things may make you a success as entrepreneur. But it's by far not to be singled out as The Major Factor.
