The way I see it, though, it is not the bureaucrat’s job to be better at making decisions for children than the best parent, or even than the average parent. It is the bureaucrat’s job to create a floor; to ensure that no child is treated worse than a certain level.
It doesn’t (and can’t) work this way in practice. In practice what happens is that there is a disagreement between the bureaucracy and the parents. In that case whose views should prevail? If you answer “the bureaucracy’s” your floor is now also a ceiling, if you answer “the parents’ ” you’ve just gutted your floor. If you want to answer “the parents’ if their average or better and the bureaucracy’s otherwise” then the question becomes whose job is it to make that judgement, and we’re back to the previous two cases.
