Regarding the last point (the cloak being special): Well, it belonged to Harry’s father but he gave it to Dumbledore for savekeeping. That alone is evidence that this is not just a normal cloak with a simple charm on it, which you could just buy again, if you lose it. Ron even says that such an invisibility cloak is extremely rare and valuable.
I’ve always wondered about that. You’re in the middle of a deadly war, and consider yourself to be in such danger that you use a rare and powerful charm to make your house not exist for the uninitiated. Why do you give away an invisibility cloak, normal or unique, and why do you give it to someone who explicitly states “I do not need a cloak to become invisible”?
