We have the concept of a "state of emergency" for a reason, to temporarily give the government additional power to deal with emergencies.

We don't want a completely powerless government, we invented government and endowed it with certain powers for a good reason. That's why states of emergency, etc, are temporary and time limited because we are aware of the tradeoffs and downsides of additional govt power vs catastrophic immediate necessity.

If I lived next to an active forest fire, I wouldn't want the govt to commission a 36 month study to determine whether the fire was spread along the ground, or via airborne flaming leaves and embers. I would want them to put it out, even if that meant exercising temporary emergency powers like closing a road or shutting off a power line.
