That could be true. However, I have to wonder if coercion is truly 'easier', or, more precisely, if coercion is indeed economically rational? Isn't war costly? Does not a coercive person have to pay the cost of living in constant fear of revenge and retribution? In other words, could it be the case that coercion is actually a more expensive, hence, economically irrational way to live than voluntary peaceful association? Could it simply be that people mistakenly hold the belief that 'coercion is easier'?
