People will have drones of their own, which will run into and crash swarm drones.

Remember the key here is that in the swarm the drones coordinate their efforts and movements with each other. It would be too easy for an “enemy drone” to be taken out before the entire swarm of 100s are all taken out. Not only that it is very easy to keep adding 100 more to the swarm to join the “fight”.
