If you expand this transaction to an entire economy, I think this is in the neighborhood of how a central bank works. Sora XOR is/was an attempt in this direction, where a smart contract central bank buys and sells XOR on a curve to respond to economic demand. (The price crashed before it could collateralize the curve, so afaik it's never functioned as intended)
