—“All money is someone’s debt backed by a promise to redeem the debt. When the money is issued by the state, then you have its vast assets backing its value and so liquidity is increased compared with individuals issuing currency. This is why the sovereign often appears on the currency.”—-

Nope. credit money might be. But commodity money is a store of value already produced. That is what separates commodity money (value stored), fiduciary media (value borrowed), and credit money (value promised), and fiat money – meaning shares in the economy (future value speculated upon).

You are using the term ‘money’ by cherry picking properties to suit your argument.

The diagram above lists the categories of money from commodity through trade credit. Money = commodity money.

Everything else is a substitute of decreasing liquidity of temporal value.
