I should not be coerced to give output of my labor (whether physical or mental) to others based on some burocrat’s allocation system or my neighbor’s wishes. That would be immoral.

Per your morality perhaps. But morality is just an opinion, and one that can't be justified otherwise.

I should not be coerced not to enter a piece of land just because somebody made a contract with somebody who killed or evicted by force the people (and other animals) who previously inhabited the land. That would be immoral, right?
