I think overall, the idea of money is messed up on many levels. What we call 'money' today doesn't even have an identity. It's the most important thing in the world, it's also the most heavily utilized thing in the world but almost nobody knows what it means.

- It's backed by nothing.

- It's not a fair medium of exchange because it physically cannot circulate very far from 'money printers' (not many hops) before it's taxed down to nothing. This means that it's unevenly scarce based on social proximity; unfair by design. Cantillon effects on steroids.

- It doesn't even exist as a single cohesive concept; the US dollar in your bank account is not the same as the US dollar in your friend's bank account and it's not the same as the US dollar which European traders use to buy derivatives (e.g. Eurodollars)... There are literally thousands of different ledgers (banks, institutions, in different countries), each presenting its own interface supposedly showing their holdings of this mythical unit called 'The US dollar' which is actually thousands of different currencies, which happen to share the same name, scattered around the world and held together only by regulators whose only shared interest is to print more units for themselves than the next guy does. Slow and fallible human regulators represent the only layer of 'consensus' which exists for the entire fiat monetary system; they move at snails' pace in a world of high frequency trading.
