I'm not convinced that the policy you propose

I haven't made a proposal. I've made a statement about who I trust and also rejected 'best for a particular majority group' as a reason that I should personally support a specific brand of coercion.

(children get the last word)

This is different from 'parents can force a child to take psychoactive medications against their will'. In the latter case may be tempted to assign policy for at what age this 'parental right' expires. It would be less than 17. It would also apply to a far smaller set of situations than that for which psychoactive medication may legally be offered or recommended to or by the parents.
