There are two kinds of true, and thus two kinds of ‘real’ to think of. There’s the kind where what you believe matters and the kind where it doesn’t. Gravity is the second kind. Step off the top of a building and it doesn’t matter if you believe in gravity, you’re going to fall. Politics is the first kind. If everyone believes I’m the king of North America, well, then that’s the truth. It’s reality. Likewise if everyone in the government believes that Elon Musk can fire whoever he wants, then he can, because everyone will just go along with it.
