Except you don't know any successful people who've remotely done what he's done either.
Talking about 'Dogecoin' is a little unseemly, but it's nowhere in the realm of 'toxic' or 'bad acting'
Without massive public support and sympathy, Telsa wouldn't exist, it's a movement as much as anything, and so you need kind of a showman.
His appearances on SNL etc. are part of that public drama that keeps Tesla stock going with enough support to keep the legitimacy of the dream alive.
I'm seriously doubtful that a quiet, unassuming person would have been able to do most of that.
Expressive, bombastic characters will by virtue of the volume of their actions, sometimes creep up to the line. It's normal. There's nothing wrong with Elon, he's just a little cheezy and spouts too hard with some things.
I think that's a BS excuse for bad behavior. How would being polite and concientious harm Tesla? It's simply that he has power and has low standards for his behavior.
I know plenty of successful people who do what Musk fails to do.
