On one hand, this is a momentous day for private space flight. On the other, we're closer to Moon lobbyists than ever.

(And for those inclined to take that as their cue to strike the fashionable misanthropic pose where they claim that would be a good thing, remember: The moon is a dead, sterile rock. The Moon has no copyright law because there is no creative activity of any kind there taking place that could be copyrighted. There is nothing there to abuse, no "environment" to foul, no natives to exploit, nothing, not even bacteria. The alternative to humans going there is death, forever. And not "human" death, either, but total death. No life. Deader than the worst possible nuclear holocaust could ever make Earth. If that is truly your position, fine, but I hope I can at least remove the fashionableness from your pose.)
I agree with the sentiment of your post, but this is incorrect. The Moon is a uniquely pristine environment that holds irreplaceable evidence regarding the formation of both our and other solar systems. It may even contain bacteria, trapped long-dead within meteorites, that could tell us more about the development of life on Earth or elsewhere.
It is of huge importance that we are able to extract as much of this information as possible before we start tearing it up.
Also an entire solar system and indeed an entire universe full of further such stuff.
Space is big.
This is a terrible argument.
By the time we've "wrecked" all that precious precious data about the formation of the solar system we'll have better recording equipment than we can even dream of now anyhow, since we're talking centuries and centuries from now in the "best" case. Not to mention we'll have visited a few other places in this case.
That aside, here's some elaboration.
Trillions of meteorites have landed on the Moon's surface since its formation. Some of these may be remnants from violent collisions between other planetary bodies. A few of these events may have happened at a time where life was starting on Earth. An tiny portion of these pieces of rock may actually contain fossil evidence of early life, in the form of bacteria or complex biochemistry. Similar evidence that once existed on Earth is likely to have been destroyed by our active geology, or by more recent biological processes.
The likelihood of life being preserved in this manner is so vanishingly small that, out of the trillions of meteorites on the Moon's surface (an area around 20% larger than that of Africa), only a minute number of them are likely to contain anything like it.
It would be a shame if the key to understanding abiogenesis was lost in an industrial rock-grinder.
