Yes. Fortunately, the shock absorber can do a hell of a lot on its own. In fact, of the two components - shock and spring - the shock has far, far more control over what's going on than the spring does. The springs really just adjust balance front to rear and limit body roll to an acceptable level. All the dynamic stuff is handled by the shock. That's why things like active shock absorbers are so cool and useful.

And if the droop was never used during driving, what's the benefit?
Think about it a different way - after a bump, the chassis moves up. If you only have bump travel your wheels are going to come off the ground, even if it's only a little bit. Droop is used after bump. And the droop travel really is used a lot during daily driving.

I understand you need compression, but is the droop really that necessary for tarmac (non-jumping) use?
Not as much, but yes. How about this - if you're cornering and you have 2" compression on one side and 2" droop on the other you're using 4 inches of travel. Then you hit a bump. Now what? If you only have 4 inches of travel, you're going to go off the road, either through sever overloading of the outside tires or through unsettling the car by suddenly unloading the inside tires.
