Changing economy of the target system changes the clean Items that are delivered to system..
Population count changes how many ships are going to hit that system with high price items... this lowers the wait time for the high price items...
When you combine that with Anarchy controlled station you change the drop table of items that can be stolen with no risk... Each economy changes what you can steal as they are delivering legal sale items not just illegal or smugglers...
There is no requirement to sell were you steal from... If you use a high jump range anaconda You sell any were... use cutter and you don't have to sell untill after the T7/T9 shows up normaly...
Traders will run now, they don't want to fight any more , that old action was changed, was forced by fdev, so you don't even have to build for defence...
The best cargo also is not insured to be on cargo ships... Fighter builds will carry clean cargo as the normal trade dropped ship...
Don't check every ship and you can miss the good cargo drop for that cycle and thats the issue with RNG ships as delivering trade goods...
Dam Anaconda as NPC cargo ship... If I had skipped him thats the good drop missed...
