The tradition of hunting has always been a legacy born out of necessity typically passed down from generation. If you didn’t hunt, you didn’t eat. There was no earning anything, hunting was just a lifestyle. Only until recently (the passed hundred years or so) has modern man been able to survive without hunting. So there was no earning the right to hunt. There was hunting and therefore surviving and the only other option was eventual death. And who is going to determine what it takes “earn” the right to hunt?
