I appreciate the sentiment, but consider the economics-- those 10 missiles would destroy how many millions or billions of dollars (individual lives aside)?

Each DPRK nuke that makes it through represents a neighborhood evaporated (30kt yield will destroy most structures within a 1-mile radius).

Now imagine even higher yields making it through.  The cost of R&D/deployment for missile shields is usually compared to the consequences of zero defense (in light of the potential threat).
