The https://en.wikipedia.org/wiki/Outer_Space_Treaty#Provisions https://en.wikipedia.org/wiki/Outer_Space_Treaty#Provisions (whose signatories include BR,CA,US) requires that installations on the moon (and other celestial bodies) be used for peaceful purposes, so I guess we'd have to rely on the Amish brain control not resulting in violence — but seeing as how all the violent anabaptist sects have already died out, leaving only the pacifist ones (among which are the Amish), that may not be that bad a bet. (TIL that Amish —in order to avoid unneeded sewing time— wear cotton/poly clothing, and of course they're not synthesising polymers at home and therefore have to buy that fabric from the english, so the brain control space lasers are even more plausible) (Edit: Amish horseshoes may have carbide and borium additions, again for durability)
