Your description is not of a genius but more a "commercial community organizer" who organizes people and then negotiates between a company looking for cost reductions and State&Federal Governments to subsidize.

This is not genius-level but is the blending of two skills, a charismatic Administator, who can temporarily suspend disbelief, and a Fundraiser. Each of those takes a ton of work. I'm not minimizing Musk's dilligence in any way, but there are lots of people who can do those activities at high levels. The difference is that most people can't survive their tweeting SEC violations while stoned.
