Not enough of it, not hooked into the right systems. It works for Elon Musk because he has a lot more and because he controls critical piece of infrastructure (starlink, SpaceX) that the defense industry needs.
He's also not old money or especially supportive of old money; he's just some script kiddy who scammed his way to the top on the back of the kind of confidence that tends to only come when you're built like an NFL lineman but can also read documentation. The seethe is easy to understand.
