Even without the power to fight, they could adapt, endure, and keep the system running.
If they stopped doing what they were doing, the supernatural society would break, and the supernatural influences like the Spirits and Evil Spirits would likely end up gaining the advantage once more.
If the Balancers were the sword, and Watchers were the eyes, then the average human worker would be the heartbeat.
If the heartbeat stopped, the sword and eyes would have nothing left to fight for.
It was not just their influence on the supernatural world that was important, as they could play various roles in the ordinary world that could be just as important and useful in many ways.
Ignoring any of them when they had a connection to both worlds would be very unwise.
Even ordinary people in an influence like the Eternal Balance Church played some role.
