People started companies and succeeded for dumber reasons. Generalized "businessing" skills and placing yourself somewhere in the space where money is made counts for much more than actually knowing anything about specific product beforehand.

That's a very good point.

I would add, that sometimes being a newcomer is a benefit. Many times a particular industry is stuck in groupthink, having shared understanding on what is and what isn't possible. And it sometimes requires a person with a fresh perspective to be able to upend it. See example of Elon upending multiple industries by essentially doing exactly that.
