There's essentially two options
Premise: A speedier ship that can mass lock me has successfully interdicted me and demanded me to stop.
Choices:
1. Cargo/Dignity is worth keeping more than my life, therefore you engage in combat (regardless of win or loss).
2. I don't want to waste the progress I made so far, the pirate most likely will not ask for everything I have (even if the pirate does, you still don't have to pay for your insurance if you chose option 1). So, I will comply and most likely fly safely to my destination.
This is similar to the prisoner dilemma. The best choice is always 2, therefore just comply for the best result.
