Reading this thread through makes me think that perhaps you’re not familiar with the way that state school admissions work?
To be fair to the OP, the rhetoric of 'school choice' obscures how state school admissions works for many.
Parents are led to believe that they can choose a school for their child, and in p[articular that they can choose AGAINST a school that they don't want.
In actual fact, in probably the vast majority of cases, there is no, or very little, choice, or rather there is the choice of 1 'obvious' school (the nearest / the right one for the christian denomination / the catchment school) or perhaps further away, maybe rather poor, undersubscribed schools.
OP, what the admissions form actually tells to LA is 'if, by any chance, I qualify for more than 1 of the below schools, then this is my order of preference'. So for example, I live on the absolute edge of a catchment, so my form for DS effectively said 'I know DS has qualified for the grammar school, but actually, if there is space for him in the catchment comp, that's where we want him to go, as we have put that first'.
However, if you only put down schools on your form that you have zero chance of getting your child into (and a few minutes on Google will tell you that), then the council has no idea what your 'least worst' realistic choice is, and they will simply give you the space that everyone else has left. It is a computerised process. There is no human judgement or preference or 'ooh, I like the sound of him' involved - the computer applies the oversubscription criteria dispassionately, and churns out an answer.
