Unfortunately there is almost no carbon or hydrogen on the moon with the exception of trace amounts in permanently shadowed craters. Self sufficiency is barely possible in those areas which comprise less than 1% of the moon's surface.
As the article says, the moon has water, and that means hydrogen. Regarding carbon, it is an abundant element in the universe, so I would expect there would be a good deal in the minerals.
"Know" ? According to Wiki, "scientists have conjectured since the 1960s that water ice could survive in cold, permanently shadowed craters at the Moon's poles." https://en.wikipedia.org/wiki/Lunar_water
That article is full of qualifiers. Considering how much thorough science is found in WP ... and the -strong desire- many feel to verify this as fact ... where's the beef?
We "know" Mars has methane, too.
Suppose there really is water. In what quantities? Where? (If they don't land near it ... transport?) Who is going to -bet their life on it- ??
I've never found a definitive source for this "know". I'm all eyes.
