Quantity vs Quality.
All of your points are true, but they are arguments of quantity over quality. You have more books, you can write faster, etc.
Especially at an early age, students benefit from an emphasis on quality over quantity. Real books, with subjects read slowly and studied in depth. Thoughtful consideration before putting pen to paper. Taking physical notes. (I absolutely hated taking notes in class but it has a documented relationship to remembering the information.) etc.
Introducing computer-aided learning tools such as word-processors and e-books and tablets and search engines is important as it allows faster processing of more detailed and up-to-date information, but the basics need to be developed first. Speed running the educational system does not improve learning.
TLDR: physical books and handwriting good to start with, add electronics in higher grades.
