Your (eternal) error is to think that monetary assets HAVE TO be backed by something.
I don't think I've stated or implied that ever.
I've always said that Bitcoin is an unbacked asset and that that's its value basis - same as precious metals, diamonds, whatever.
The point about backed vs unbacked is that in a so called bearer token or "bearer instrument" there is not a distinct definition of ownership and possession. Assets which are "backed" therefore specifically trade ownership and are consequently subject to privacy/security priorities where obfuscation is appropriate since they only manifest in a record-keeping context.
The "IOU" tokens you trade on an exchange are such backed (contractual money). The blockchain tokens are not.
