The MAP on an ILS is the DH(A), it is defined as a point in space where the DH and the 'on course,on glide path' intersect. If you fly the GS to a MDA, there will be not defined point at which to execute the missed approach procedure--you would have to make one up by combining the LOC procedure with the ILS procedure. Yes, I agree, if you cannot see the runway/airport environment, one would have to go missed, but where abouts?
