I've only met one billionaire, but he was definitely not guarded by anyone, and had I the inclination, skills, and firepower, I could have easily taken him at gunpoint.
I don't accept the notion that Jack Ma is guarded 100% of the time, that's movie fiction.
Some billionaires are relatively unknown, so maybe they get away without needing that.

That's a very big "had I", and certainly not "anyone with a gun" as you said previously.
Let me put it this way: suppose you're Bezos or Jack Ma and had access to unimaginable resources, comfort, and security from the best of the best. Surely it would be absolutely trivial to hire someone so that the vast, vast, majority of people with guns wouldn't be able to get to you, no matter how hard they tried, even _with_ so-called inclination and skills?
I'm not even referring to having guard detail around them all the time; when you're that important and hundreds of billions of market cap depends on your very existence, their entire schedules will be mapped down to the smallest detail to minimize risk of harm to them, since if they were to get kidnapped, it would immediately wipe billions off the stock price. Do you really think that the only reason Bezos hasn't been captured is because ordinary people with guns just chose not to do so, and if anyone wanted, they could just kidnap Bezos easily? What percent of ordinary people like you or I have "skills" and "inclination" that can beat that hired by Bezos' billions?
But message received -- Jack Ma probably would have a team of bodyguards, and the people who could get past that probably wouldn't need to manipulate markets using his appearance on a conference call to make money.
I was wrong, I see that now!
And we're talking about state-level actors here doing the holding, not some random nobody with a gun. Those don't have any need for "insider trading".
