Earlier quoted context omitted.
I think it's dangerous to assume that kids neither have individually nor anything interesting to say. Just the other day my 3 year old was explaining to me how cars, tablet PCs and people all need different types of energy to function. I found that conversation to be far more interesting than half the discussions I have with peers of my own age.
OK, so what about point b - by prioritising children expressing their individuality we are actually limiting their ability to express themselves with eloquence?
It doesn't happen. You're wrong. You're being very firm with your assertions, but they're based on something that doesn't happen.
Have a look at common core standards for English. Most of them have nothing to do with "expressing their individuality", but about introducing a topic, making an argument, and supporting it with evidence.
