Actually the BHG aren't the best selling pilots in house space.
And next time you post something like that about trade routes or selling locations include a spoiler.
Some people actually want to find stuff themselves, although theres also alot of people who'd rather be given everything because their too lazy to find/look themselves.
As to the rep problem you pointed out, well, I really don't see what the problem is.
So far only the phantoms have RP'd neutral status with the nomads which doesn't extend to the game itself.
So, yes they might RP helping the nomads or landing on a nomad base, but ingame they still get shot at by them.
Besides which as theres no dealers or anything on any nomad bases, of which the nomad lair and dyson sphere would be the dockable ones.
The nomad lair is just a giant tunnel so you can pick up the nomad powercore in the SP campaign and the dyson sphere is just access to the nomads home in SP.
So theres no point in being able to get neutral or friendly status to the nomads.
Takagi's arch is owned by the corrupt kusari navy, not the nomads, so even with a neutral nomad rep you still wouldn't be able to land there.
