Not many areas are isolated in Yamani, other than a few areas on L-07. During Jane's one year of wandering, it was something she realized long ago. All beings can be freed to do anything and get light punishment even if they make a violation, but humans. When the human race commits an offense for the sake of their own race, then the punishment they get will be very heavy.
If other races did that, or even tried to destroy the human race, there is no law against such a thing. After all, here, the human race was not considered a creature worthy of life. They are only limited to food.
There is no privilege in treating food ingredients.
