Yup. Money is weird.
Measurement of value, accounting of debts, commodity to be collected.
David Graeber's book Debt has a pretty good survey of our evolving, manyform, paradoxical thinking towards money and related metaphors.
As for crypto currency, I mostly agree with Mark Cuban's conclusion they're collectibles. Ergo, they're useful for escrow use cases, like exfiltrating money and swapping assets.
I'll believe crypto currencies are proper money once a government accepts them as payment for taxes.
