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 a beneficial and **self-sustaining tradition** in which it has a special place. Its properties enable this, but don't guarantee it will arise.
The same applies for Bitcoin.
