It's only coercive when you adopt some backwards conception of what coercion means. (E.g., The rapist claims they are being coerced because they can't do whatever they please with other peoples' bodies.)

I'll agree that there are many ways in which the status quo contains injustice as it relates to claims of ownership, but that's entirely different than calling the system of private property coercive. I also don't think there is one objective standard for what confers just and unjust title (i.e., I think this is an emergent social convention rather than some clearly definable concept), but that again is an entirely different topic.
