What's the benefit of killing tech structures over drones? I mean, apart from the obvious. Why is it better to kill say a Hydra den than to kill 5-10 drones? Economically, I would have thought that the drones would have been better?

The only time where i have seen protoss use them is in the lategame, to me it seems like a tactic to come back from behind, in the late game a zerg will have 2-3 spines and a spore at every base but it is not yet common to build them in the main, sniping the main lair/hive will stop overseers from being morphed in and give you a large period of time where it is hard to be attacked.
The other reason is key tech structures like infestation pit and greater spire have been really hard to deal with for protoss lately, and when a zerg is maxed killing drones doesn't really mean anything because they can just rebuild them.
