No one that has looked at this in a serious way agrees with you.
From the abstract:
“These results suggest that the movements involved in handwriting allow a greater memorization of new words. The advantage of handwriting over typing might also be caused by a more positive mood during learning. Finally, our results show that handwriting with a digital pen and tablet can increase the ability to learn compared with keyboard typing once the individuals are accustomed to it.”
See my comment to OP for a recentish publication that shows the same thing all studies previously have shown. You are quite correct.
