There's another ISRU propulsion scheme that could work out with Moon, if oxygen+hydrogen proves to be infeasible due to difficulties with extracting the hydrogen.
Aluminium-based solid rockets. There's plenty of aluminum and plenty of oxygen, although its obviously a lot more energy-intensive to convert to useable propellant, than it would be with water ice.
