True up to a point, but the agriculturalists are able to support far more human flourishing on the same land - hence why they won the fight. And AIUI for much of the time when both existed and were in conflict, the pastoralists were essentially parasitic on the agriculturalists (in that they were taking more by raiding than they would ever have gained through hunting).

Formal, documented slavery perhaps - but that's because those are the only societies with formal, documented anything. How much choice do people in those societies have of what kind of work to do, much less not to work? How much choice do women have of who to marry, much less not to marry (and how much choice of how they're treated within that marriage)? Of course you can choose not to follow the customs of your tribe, but at that point how much protection is there for your property or even your life?
