yes, I agree there that nothing provides 100% protection. The iron beam maybe adequet against mortar shells but against warheads with proper shielding, that too may not be enough. So basically your saying the same thing that I am...it eventually becomes a slugfest, a numbering game of attrition. And the advantage that the attacking side is that incoming shells, rockets, missiles, drones, etc. what have you are relatively inexpensive as compared to the intercepting missiles which are bound to be far more expensive and thus harder to make or purchase.
But agreed that it gives the population enough time to run for cover.
Swarm of drones ain't that easy to deploy, and beside that, methods of interception of such targets have been developed already.
Proper missile shield give u the advantage to defend your critical assets while attacking enemy targets.

IAI UNVEILS "DRONE GUARD": DRONE DETECTION AND DISRUPTION COUNTER UAV SYSTEMS
Oct 19, 2015
The systems will be presented during the Seoul ADEX exhibition
Israel Aerospace Industries (IAI) will unveil the Drone Guard- new systems for drone detection, identification and flight disruption - during the Seoul International Aerospace and Defence Exhibition (ADEX) which opens this week (IAI at Booth #C-53).
The use of small drones has increased dramatically over the years, making them a potential threat to critical infrastructures, other aircraft and homeland security (HLS), due to their small size, low speed and low flight altitude. These drones may be used for a number of reasons, including hostile purposes such as intelligence gathering, smuggling, or as weaponized platforms. In addition, they are difficult to detect or disrupt due to their low visibility and low Radar Cross Section (RCS).
To meet this emerging challenge, IAI's Subsidiary and Group, ELTA Systems Ltd., offers specially adapted 3-Dimensional (3D) radars and Electro-Optical (EO) sensors for detection and identification, as well as dedicated Electronic Attack (EA) jamming systems for disrupting drone flight.
To detect low signature, low-level and low-speed airborne targets, ELTA has adapted to this specific mission its 3D radars, which include the ELM-2026D, ELM-2026B and ELM-2026BF for short (10km), medium (15km) and long (20 km) ranges, respectively, with special drone detection and tracking algorithms, as well as adapting them with EO sensors for visual identification of the target.
In order to disrupt the hostile UAV, ELTA has developed advanced adaptive jamming systems which can be used in concert with its detection and identification sensors, or as a continuously operated stand-alone system. The jamming disrupts the drone's flight and can either cause it to return to its point-of-origin (‘Return Home' function) or to shut down and make a crash landing.
"Drone Guard" systems have been extensively and successfully tested against a variety of different drones and scenarios, including simultaneous multiple drone penetrations or attacks.
Nissim Hadas, IAI Executive VP and ELTA President said: "We have begun demonstrating these novel capabilities to potential customers, in response to this new threat. We believe that in the near future every critical asset and public site will require these safety measures for protection against hostile drones".
