The thing about the floating nodes is not necessarily true. All the Sx nodes have a DC path to ground via the FET body diodes' GMIN and the load. Also, the G-source doesn't add too much to the circuit matrix, but you are technically correct. Actually, it would be the most computationally efficient if the voltage source was removed and the G-source was turned into an independent current source (I-source).
