That's the whole concept of an ILS - that is so precise that you will not hit anything but the runway.

Not true. A Cat II ILS requires a visual segment to ensure you are at the runway. For the more precise CAT III B with no DH is one of the options.

It is possible that the A/C will miss the landing area when doing CAT II hence the requirement for a visual segment.
