Anyone with more than a 9 figure net worth usually has multiple full-time bodyguards. That's also because there are usually psychotic randos that are stalking them if they have any kind of fame. It's a trivial expense at that level of net worth. Public filings from Facebook show that Mark Zuckerberg spends $10 million annually on personal security. Elon said at Twitter he doesn't even go to the bathroom without his bodyguards.
