How do you think the other people can a) build houses, grow, and prepare food effectively, and b) know what houses and food to prepare to provide the most benefit? Communication and organisation are extremely valuable, even if the structures we set up are not the most efficient at doing so and may have a tendancy to create their own busywork (but computers have made that efficiency skyrocket. You're paid so much because you replace a small army of people shuffling paper around, and there's not enough people who can do that well).
