The foundational fallacy is that people try to explain money in physical terms when it is purely a sociological phenomenon.
Gold is not valuable because it is durable, fungible, portable, and scarce; it is valuable because of the **self-sustaining tradition** around it.
Its properties enable this, but don't guarantee it.
The same applies to Bitcoin. It’s why you can't copy Bitcoin's value by forkingthe blockchain and adding extra features - the shared socially-reinforcing belief of billions of people is impossible to replicate.
Similarly, if a new metal better than gold was found - it wouldn't inherit all its value.
