On the subject of using the Moon's resources, that's a good idea once you're on the Moon. It doesn't get you there. You still need to launch many tons of propellants and consumables from the Earth to make it to the Moon in the first place.
And I would add if there is H2O ice on the Moon it is in a "concrete" form and in a very very very cold environment with "contaminates" such as ammonia ices...
