If this was actually a security threat, the man could take chartered flights anonymously forever with a rounding error's worth of his money. Opsec is clearly not important to him.
It's the Elon show. He needs the attention and doesn't care if it's positive or negative.
I find it absurd how many people are against automated license plate readers (even privately owned ones) but simultaneously welcome the complete lack of privacy for aircraft. If someone replied, “Just use a taxi/Uber/Lyft.” in response to ALPRs they’d be downvoted into obscurity, and rightly so. But change the transport mechanism and suddenly it’s fair. The hypocrisy could not be more obvious.
He created this 'problem' out of nothing. It's an act. If he feared for his family's safety there are ways to tackle the problem that aren't purely performative.
Credit card transactions also aren't protected from marketing tracking activities, neither are Twitter or Facebook ads, neither is what my isp can discover from my dns requests, cell phone providers can sell my location metadata, and the credit bureaus are ordinary businesses with huge data leaks.
This is public information, police can operate on it without a warrant, and whether we're driving, flying a private jet, walking in a town square, or purchasing a coffee, or browse the internet - other private entities can too.
LifeLock and identity theft protection are sold to everybody, tax forms allow anybody to try to use someone else's number - the government refuses to do anything, and companies have minimum privacy + security requirements.
What would it take to change your mind about this? There have already been close calls. Would someone actually have to harm Musk or his family? And you didn't address my ALPR analogy at all. Why does it matter whether the mode of transportation is a car or a plane?

There's also no context in that video, it's just a clip of a person in a car. I do not take Elon's word for anything, he's demonstrated over and over and over that he will act in bad faith. The one party he probably would/should not lie to, the police, doesn't seem to have any report from him about this event.
