Money is a completely fictitious entity, but it’s very powerful in our world; we each have wallets, which have got notes in them, but what can those notes do? You can’t breed them, you can’t stir fry them, you can’t live in them, there’s absolutely nothing you can do with them that’s any use, other than exchange them with each other – and as soon as we exchange them with each other all sorts of powerful things happen, because it’s a fiction that we’ve all subscribed to.
