DUDE, you took THREE missions and had THREE NPCs after you. You even complain about that.
You could stack missions before without any problem. No factions selling you out to their competition. Are you going to tell me that I should sit in a station with 200 free cargo space, see 4 missions for a total of 20 cargo space all going to the same place, and just pick one of them for pittance? I'm guessing in your 'years' of playing you're at the point where you don't need to grind faction or money any more, since you were able to do it when you could grab as many missions as you wanted. Or you're in that high tier ship and able to effortlessly kill off everything that comes close. Or never crossed into the higher combat ranks. But not everyone is in that state.
No, I would not remove interdictions, but it does make it a bit of a stretch of the imagination to have a small army out there trying to interdict and kill you (from different factions) just for sake of the 6 clothing, 4 food capsules, and 10 hydrogen fuel you happen to be transporting. If it was tied to running cargo to a station in conflict, or was a rare occurrence, that would be fine. But it's literally every mission you take has a random event component that is usually always pirates. It's the frequency of occurrence that is the problem, not the intensity. 'Chance' of pirates in a high security system should not be a certainty, time and time again. As you seemingly are someone with a very black and white mentality, you probably won't understand no matter how it is explained.
The current system does nothing but make mission grinding more tedious (unless you're taking combat missions) and punish heavily for using anything other than a pure combat ship. Just because you don't recognize the idea of hauling as something people intentionally want to do, does not mean that forcing frequent and near constant combat is a good solution.
lol gotcha you meant rare data
Rare data as in engineering materials... Stuff which has no value to pirates, which you cannot transfer, which you cannot sell.
Had the same thing where a pirate interdicted my exploring ship that has no cargo space of any kind and decided to open fire on me for not dropping my cargo.
