Wildlife versus Livestock
Wildlife is free to pass through borders without authentication. Birds can fly from one country to another without a passport.
Lifestock must bear the Mark of Authentication in order to pass through borders. Cattle and sheep must be branded, marked, or submit to a biometric database before they are allowed to pass across a border.
Members of the wildlife community are free to help each other, and to form mutually beneficial relationships.
Members of the livestock community are only free to help each other but only if they also offer a portion of that help to their master. In order to facilitate the aforementioned "only if", all manner of help shall be quantized through an organizational mechanism known as "commerce".
