The serious problem with Pirate - Trader interactions is that pirates are separated into cool pirates who demand REASONABLE monies and RP, and (bad word ) pirates who demand 50% of the profit. Maybe adding back sirius credit cards to NPC traders would be a good compromise as pirates would make money by killing NPCs when there are no players around. Nowdays being a pirate isn't really profitable and fact that some of them are (bad) discourages traders to interact with pirates as a whole
Just give 2mil sirius credit card for NPC transports and pirates will demand lower monies --> traders will want to speak with them
