Over sensitive much? Wowza - what personal attacks? I was attacking the typical interaction on this dumb site, not you specifically, but your response just confirms more the typical response to differeing opinions regularly spewed on here...
Secondly (also typical - try not to let that word get your diaper worked up) - you have taken stuff I have posted and completely and (conveniently) wrenched it out of WAY out context and melded it to make your argument (another regular Redditor tactic, instead of just tactfully agreeing your point is not totally correct or indisputable)...
Yes PARTICLES - look at my very first post dude - I said "STUFF" - ie - anything hitting the surface of the moon with velocity. You keep reverting this back to one article on a "meteorite" as if that is the only thing flying around on the moon... and extrapolating whacky stats on that one meteorite to make your point. Meanwhile tons of "stuff" that can do damage hits the moon and is churned up on the moon daily.
AS far as "tempering my fears", honestly all I did was raise a skeptical question that any pragmatic business person would. Does "stuff" hit the moon? YES. Does it hit the moon regularly? YES. Can it cause damage to structures? YES. Does it hit the moon frequently enough that NASA expressed concern for the protection of future structures? YES.
I mean seriously dude??? You are going to keep debating this on here? What, do you have skin in the 3-D printing game or something - are you their PR hack? It sure sounds it...
No business person in their right mind is going to dump millions of dollars into build structures on the lunar surface until they reach some level of assurance they are not going to be destroyed...c'mon now it's common sense. On Earth there flood plain studies, flood insurance - the environment it pretty well studied as far as where is it is safe and practical to build at - the comparison is apples and oranges. As recent as October, they still were not even sure how frequently "stuff" hit the moon, and I would guess, they still aren't not to mention other unknown building hazards up there. Give me a break, the debate is silly.
