> A curious mind will develop critical thinking skills.
This is the linchpin of the debate.
What if the first book you read at a critical age insists that it alone is true, and that other books should be distrusted at risk of harms to yourself? Say, the Christian Bible.
It is absolutely possible -- unlikely, given the subjects of most books, but possible -- to have harmful information encoded in a book.
The question is then how to blunt those negative outcomes, at scale, democratically, without opening the door to arbitrary political interference of the day.
