What's wrong with coercion?
Define fraud.
Where does the libertarian principle come from?
The stated assumptions are that all people are equal with respect to morals; that morals apply equally to all persons; that individuals are sovereign. If it is not immoral for me to initiate force against another, then it is not immoral for another to initiate force against me. Since I do not wish another to initiate force against me, I may not initiate force against another. Coercion is the threat of force. Fraud is willful deception during a transaction, usually for the purpose of disproportionate gain.

You said that if God did not prohibit murder, then he would not be God. Is God constrained then to only approve empirically moral actions? How is such determined? Could God approve of an immoral action?
I've answered enough of your questions. You start answering some of mine.
