The answer is electricity. It's so useful, we take it for granted. Your phones, computers and laptops are not useful if you can't power them.
I'll give the people on the dunny their due: toilet paper is still useful in a room without electricity.
Your point is a good one, though I'd like to point out that electricity is so useful that if I have power and water in the room (and a bit of prep time) I can make oxygen.
