While I understand the idea of a city-wide barrier, my question is:

If a single, or even a small group of people is maintaining this barrier constantly, how is it not decreasing their life force?

As it is creating a barrier the size of a city is extremely taxing and time-consuming; Freed showed that.

To maintain that barrier constantly without some sort of trade-off seems silly, to me.
