I would add a reason for Harry to have the wand.
Like, instead of, “You will not raise your wand”, “You will only raise your wand when and how I permit it. Do not demonstrate a spell unless ordered.”
That would imply that Voldemort was open to the possibility that Harry might demonstrate something, which would require arming him.
We operate in an environment of government basically functioning to such a degree that we don’t notice it. Why is news about government dominated by government breaking? The nature of the role of government is usually to prevent bad things. So, when it does extra-well, no one can tell. If we note these actions, what do we get? Focusing on what has affected me personally:
Police can probably take some credit for the following:
I have gone 3369 days since I was last robbed; my family has not been robbed.
I have gone 7960 days since I was last assaulted; my family has not been assaulted.
The police and fire departments assist the (non-governmental) rescue squad
Though annoying when it must be done, the roads and rails around me are maintained. (I do not count utility work since that is not controlled by the government here)
My daughter is receiving an acceptably good level of education
There are nice parks available to us
A nearby fire did not grow and consume our house
The sciences are supported
Something I left on the train was kept and I was able to recover it.
Of course, it could do better. In some cases, a lot better. But you were asking about the positive.
