*sigh*
Some sort of benefit?

The ice could represent relatively pristine cometary or asteroid material which has existed on the Moon for millions or billions of years. A robotic sample return mission could bring ice back to Earth for study, perhaps followed by a human mission for more detailed sampling. The simple fact that the ice is there will help scientists constrain models of impacts on the lunar surface and the effects of meteorite gardening, photodissociation, and solar wind sputtering on the Moon. Beyond the scientifically intriguing aspects, deposits of ice on the Moon would have many practical aspects for future manned lunar exploration. There is no other source of water on the Moon, and shipping water to the Moon for use by humans would be extremely expensive ($2,000 to $20,000 per kg). The lunar water could also serve as a source of oxygen, another vital material not readily found on the Moon, and hydrogen, which could be used as rocket fuel. Paul Spudis, one of the scientists who took part in the Clementine study, referred to the lunar ice deposit as possibly "the most valuable piece of real estate in the solar system". It appears that in addition to the permanently shadowed areas there are some higher areas such as crater rims which are permanently exposed to sunlight and could serve as a source of power for future missions.
Yeah. There's no benefit to water on the moon at all. Except for the small part where it effects almost everything we plan on doing in space from here on out.

Much of what they do, huh? Like what? I disagree strongly. That's not to say I think they're an efficiently functioning program. It's as bureaucratic as anything run by the federal government and I wish it was a private program. However, as government waste goes, NASA is a drop in the bucket and almost everything they do is worthwhile in much bigger ways than anything our government is doing otherwise.

Scientists can basically tell us whatever they want and we pretty much have to believe them because the rest of us are too stupid to even understand what they're saying.
Uh, speak for yourself. I've done a lot of reading in the realm of physics, astrophysics and astronomy and I feel like I have a pretty good grasp on the basics of how we know what we know. Scientists can tell us a lot of things about stars and planets great distances away. They can tell us about weather on planets that are close enough for us to make atmospheric observations or planets that we've probed. We cannot scan for life on remote planets, but we have been able to probe the surface of Mars directly, which is a little different. We know the elements present in remote stars because of the light they emit. We do not know chemical compositions until we sample them directly. That's why we had to probe Mars to find out if there was water there.
