My point is that consent is a sliding scale. Armed robbery is at an extreme point on that scale. For a less extreme point, consider your manager asking something of you in a personal capacity. There is clearly a problematic imbalance of power there. For a slightly worse example, consider sexual harassment. This is not o.k. due to the power imbalance. In general, consent given under duress isn't valid. It seems facetious to say there is a sharp line where duress ends and 'fair hardship' starts.
