For countless millennia, humans didn't need anything more except food, some very basic tools, a place to live, and other humans. You could argue that everything since then is layers and layers of bullshit. Bitcoin is just another one.
Humans did also need fuel(wood mostly). Often this was reasonably easy to get. But still involved labour. As such storage of energy that can be released at will do have value think of coal, oil and gas. These as such are not "bullshit".
Water might be other one. But now that is cheap enough, even with desalination.
I'm arguing the general point is shallow and not useful.
IMO BitCoin is designed to fail as a currency with it's mining costs, and a bad idea as an investment since exchanging it is such a house of cards. Never mind that holding any significant quantity invites dangerous people with wrenches.
