And SpaceX success comes mostly from 2 things: A) Musk not in involved in the daily running of it and B) not doing a lot of the safety stuff NASA does.
To add to your point, when Musk does get involved in operational stuff, he makes absolutely terrible decisions.
Like this year, when SpaceX was launching its Starship for the first time, Musk decided that the launch pad wouldn't have a flame diverter or a water deluge system, both of which NASA uses. He made that decision to save money, against the recommendations of his engineers.
Because they didn't have the flame diverter, the blast of the engines destroyed the pad underneath the ship. Giant chunks of debris smashed into the Starship from underneath, damaging its engines. That caused it to start tumbling uncontrollably in mid-flight, forcing the ground crew to trigger its self-destruct:

I thought I had posted this article, but I hadn't.
He did the exact same thing with moving Twitter's servers.
He refused to believe the experts who said his way couldn't be done safely, he refused to listen, did it a batshit crazy way, and fucked everything up.
It doesn't matter that he later admitted it was a mistake, that's the scary part about Musk, he considers his mistakes to be a normal byproduct of the way he does business.
He thinks it's a strength that he doesn't listen to "experts" and doesn't think the rules apply to his decisions. Because this approach has gained him so much success so far, he genuinely believes that these occasional mistakes are acceptable fallout.
The articles explains though that at his other companies, the management came up alongside him, they developed systems to try and manage him and contain him from the beginning. They figured out how to communicate with him while minimally setting him off.
Twitter wasn't run that way, so it wasn't equipped to handle Musk at all. He doesn't trust anyone there, so his default is to assume they're all full of shit and that his maniacal ideas for saving money are
always smarter than theirs, which is a recipe for disaster.
He engages in a lot of what I call "why can't they just?" thinking.
I'm a medical professional and DH is a senior government policy guy, so we're constantly inundated with "why can't they just?" questions from people. The basis of "why can't they just?" questions is that when you don't understand the complexity of something, the solutions seem really obvious.
Like "why are donor organs so hard to get? People die every day. Why can't they just harvest those organs and give them to people??"
The dumber you are about a subject, the simpler the answers to problems seem.
Musk thinks a dumb "why can't they just?" question like "why can't they just unscrew the Twitter servers and throw them into rented moving trucks and fucking move them?" and instead of grasping that he doesn't know enough to know why it's a bad idea, he just tears like a madman into where the servers are and starts unscrewing and unplugging things and throwing them in the back of rental trucks.
He doesn't register his "why can't they just?" questions as a sign of his own ignorance, he registers them as a sign of his own genius.
Refusing to accept the limitations of what is expertly understood to be "reality" is what he sees as his strength, and the fact that it sometimes doesn't work out is seen as the cost of doing genius business.
And as long as he was making gobs of money, not killing too many people, and constantly being lauded as a genius in the press, he was actually pretty justified in believing this. When the whole world tells you that your thinking is genius, why wouldn't you believe it?
It's unfathomably dangerous though to have someone with that much money and power who thinks that his greatest strength is NOT listening to expert analysis.
It's one thing to believe that there must be inefficiencies in extant systems, it's another to believe that your "why can't they just?" ignorant thinking is actually genius.
The scary part is that it means that he doesn't, he can't, learn from his mistakes.
ETA: as someone who has put A LOT of things into A LOT of brains, I'm pretty horrified that Neuralink is going ahead with human trials.
A medical device for *inside* the brain from the guy who is famous for rejecting expert safety information...sure, sounds like a great idea.
