I can't speak to his mental health, but SBF is simply not comparable.
SBF, Musk or Trump behave like privileged children that believe rules/law do not apply to them. They want everyone to know and admire them for their awesomeness, in fact it's their awesomeness that buys them an infinite number of get-out-of-jail cards.
Yes, Musk is the most useful out of all of them, by a mile. Still, the personality type/disorder is the same.
For Tesla he was an original source of money but has also been the CEO since 2008 (the same year they began production of the original roadster). So all the things people know Tesla for today (and have made it a hugely valuable company) happened under his direct leadership as CEO.
For SpaceX the idea that he is just a source of money is clearly ludicrous, given that it is entirely his brainchild. Since founding the company, he has done an excellent job of hiring all the right people that have made the company what it is today, and is clearly leading the vision and focus of the company.
I find it baffling that you're defending his antisocial and exploitative behavior.
For what it's worth, I have the same level of disdain towards all celebrities/public figures who abuse their power in this way. It's alarmingly common these days.
