Sure there's parental neglect and someone, not necessarily the state but possibly some other family member, should intervene.
There's an age of majority for a reason, if a child can enter pleas and make judgements determining their fate in this manner then how can anyone at all argue that children lack the maturity and cognitive development to avoid conscription into armed forces, criminal responsibility and possible conviction or should not be prey to predators such as peadophiles or people traffickers?
I think that they should be consulted and best interests decisions in respect of a child's care do not relieve adults of any responsibility to explain decisions to a child in a manner in which they will understand and appreciate them. Increasingly this has become a process which is, unfortunately I think, a public one, the permissive, neglectful and poorly considered cultural libertarianism has infected just about everyone and everything, so the explaining probably goes as far as friends, family, peers (of both the child and adults), right up until and including random strangers.
It seems really sinister to me that there exist trends which want to treat children and adults as alike in most or all respects, that overturns so much of human history, experience, learning and memory its unbelieveable when you reflect upon it with any degree of awareness but there's A LOT at work which aims to discourage that and instead opt for ideologically correctness.
