Bitcoin has this one extra magical property that gold doesn't: It's like gold that can be teleported across the world. That's a very powerful thing—to be able to send value to someone across the world as easily as sending an email. And, in fact, this has never been possible before in the history of the world—to be able to send value to a distant person without anyone in between, without any intermediary, such as a bank or a nation state or government, helping you out to facilitate that transaction.
