In addition to the corrosion protection that works all year round, I think of antifreeze as guarding the engine against sub-zero temperatures whilst the car is in the garage over a very cold night or a longer cold snap, or if the car has to be left outside over night in the winter for any reason - though it would be possible to drain off the water in this case, if necessary (leaving the radiator cap on the seat as a reminder). Provides peace of mind... don't like the idea of opening the bonnet to find the core plugs out on stalks of ice.
