While building ground side factories would be more expensive than space facilities, as you eliminate one to two trips through the gravity well, your space construction force is limited after the attack, but the groundside force that constructs buildings is largely unaffected.
Besides, I noted that this would not be a permanent change to the locations of factories, but temporary until the space infrastructure is rebuilt to allow for factories in space. Not to mention that the some of the infrastructure could be built on the ground and lifted into space.
And since you need to recruit new factory workers, guess where they would come from, since the huge space station that housed people is now gone? From the ground of course. So if the factory is on the ground, you don't have to build the habitat for the space factories right away nor huge terminals for a daily ground to space to ground workforce at first either.
You put factories on the ground to build stuff that doesn't require microgravity. That way your space industry that you are rebuilding can work on the stuff that requires microgravity first, while your ground factories build the other stuff. Like sections of a new station perhaps. Again, once you get far enough along that you have largely rebuilt the space infrastructure, then you close down the factories.
Yes, just waiting until you rebuild the space infrastructure would be cheaper than building factories, but you lose those months to years that Haven, the SLN, and the MAlignment are not going to give you. So a little more money, for more capability earlier is worth the cost.
Yes contragrav mokes moving things cheap, including carrying the raw materials down into the gravity well; but there is also the point that building in space is cleaner. That is to say you do not need to be as worried about contaminating planetary air or water.
I will accept that some things can be built on the planet, but those things are a minor part of the economy.
I expect that the equipment that can build factories was the equipment that was in use building space ships; and so was destroyed. But if Beowulf has that equipment, then we first put it to work building replicas of itself until there are enough new ones to begin building factories and and the new space stations. When the space stations are in place then Beowulf can take their equipment home and what remains can start producing the missiles and ships.
One major part of the assembly process involved nanite farms and it is not clear whether that will work anyplace except in space. I do think that we know enough to guess.
For those that missed it, RFC did discuss the assembly lines in an earlier thread.
