If I, guiding myself through extortion, agreed to do wrong to others for "my needs," then I would become the same as the extortionist, and continue the cycle of aggression. Putting others also, who have nothing to do, in similar situations.
Is that justified? As a thief stole me years ago, I am "enabled" to rob other people?
Don't think I'm talking about judges and courts, if I were talking about the state, then again we should admit that most people in the world are free, because they have freedom guaranteed by law, or that everyone is democratic, simply because based on the law, only a handful of countries declare themselves non-democratic.
Of course we are all human, and we make mistakes, and we would probably do immoral action because of extortion, I will not even discuss that. But the case you are raising is truly exceptional, and it does not really represent the issue we are dealing with, because it would be misleading to classify an act out of extortion in the same way as an act out of necessity.
