Okay, cool. Probably so do a lot of billionaires, at least from a pure pragmatic POV of them not wanting their skull cracked open. The point is that for a tiny portion of their wealth, they can insure against a lot of more realistic severe problems (unrest, riots, communism arising in the US, war, assassination, widespread famine), in addition to more extreme and less likely problems (doomsday, machine uprising, environmental collapse).
Frankly, were I a billionaire and able to see the choices Trump is making to make the average civilian in America jobless, penniless and hopeless, I would also be making a bunker in the wilderness or distant nation.
Yeah but you can’t though. Like let’s be real, you have 1bn, you’re not Elon Musk or Bill Gates level - and even they would not be able to stop an angry Donald Trump
