With that attitude mankind would still be living in caves. Why build a farm and stay in one place - we should follow the animals around.

1. Mankind never systematically lived in caves; that's just where remains and rock paintings are more likely to have survived.

2. Farming didn't evolve from a vision of "let's stay in one place, so let's find a way to do it"; it evolved from the gradual application of accumulated practical knowledge under real constraints until eventually it was possible to stay in one place. If Paleoelon had somehow convinced early humanity to abandon hunter-gathering and settle into a sedentary life because he had a vision for new markets around farming it would have led to the earliest famine.
