You didn't mention ignorance in your initial statement. You said
It is not an agreement when One's life depends on it... It is coercion
I would submit that if one is being coerced, one is likely not ignorant as one chooses to bend the knee to escape the threat.
In that frame, one does have a choice. Most prefer to bend the knee and collect their bribery instead of becoming a martyr.
And I contend that it is the consent that is destroyed, fully informed or not, in coercion. That's not a free choice. Consent implies no imposed consequences. Avoiding consequences is not consent.
Folks like Ghandi, Martin Luther King etc. are examples that one has consent under coercion.
I suggest that that is not (lack of) consent. That is refusing to be coerced. Yes, there is a choice between being bullied or doing what is demanded of One, but consent is not involved.
Consent is given freely, with no coercion. If it is coercion, its a choice.
