Indeed, the thread necromancy spell still works...

What was the phrase Napoleon used...making war pay for itself? Of course my head is full of useles information (ask my wife), so I might be mangling several metaphors at once. Oh well...
Corporate traders had a stranglehold on merchant activity. If you actually knew a free trader, he was (almost always) either really a spy for a merchant house/government/political faction, or he had extortion information on someone.
