"The CAPS assessment gives high marks to space-based systems. Detection hardware could be placed in Earth orbit; at the Lagrange points, nominally at one AU from Earth; even on the Moon’s surface. CAPS might also make use of existing and future ground-based assets like the Large-Aperture Synoptic Survey Telescope."

"Of course, even with far-flung space-based gear, there’s also a drawback. The placement of CAPS in space is more doable given a "down-range future", one in which space has become a beehive of activity. That means a busy space station, lots of reusable in-space transportation, command and data handling services, lunar gateways, and crew and cargo transfer vehicles flying about here and there."

A note about "beehive activity". Space is big. When we get to say population of say +1 million at LEO and beyond, then we might consider things like a future of a potential "beehive activity". I would guess that in a future in which there is + 1 million in space, most of this population with be in LEO, with thousand or so of people at places like the Moon, Mars, and Mercury. And having project type operations on Venus, outer planets, and among the millions of Asteriods. So in this situation the moon would not be the location of "beehive" but rather it will be more likely be a beehive in LEO- and a LEO with huge glaring billboards offering various things like weekend trips to new MGM Grand in a polar orbit. Though it's conceivable that advertising will be more "evolved" by this point in time and be sending their messages to a more interested & targeted audience- but I wouldn't count on it.
The traffic problem [if we are talking on the scale of 1000 or less population and a few mega mining operations] on the Moon will probably be mostly related to atmospheric pollution [adding any gas to the Moon's atmosphere]. My guess is that this won't be a huge problem- I think the Moon's vacuum will be degraded, but I don't think it would get much worse as what you can find in LEO.
Anyways I don't think the Moon is going to have a problem with overcrowding- except maybe at various tourist locations or in a few urban areas- being on Moon can still give you that feeling of complete isolation for least the next century or maybe two- even if over the next couple hills there is New Hong Kong.
