I agree! Like the author's home (Britain) there are a lot of government agencies that seem to regulate everything. However, it is interesting to note that the bureaucracy is portrayed in a very negative light and the heroes constantly fight against it as well as Lord Voldemort.
BTW, I believe the author mischaracterized or exaggerated a few aspects of the Harry Potter mythos. For example, attending Hogwarts appears to be a privilege and is not free.
Herminone is the weird one. Her family aren't witches but she knows too much inside info. She should be as clueless as Harry. It's illogical.
I suspect JK is a closet Libertarian but she'll have to play a liberal to keep her celebrity status. She owes her fortune to the media that hates Christianity. When they picked the Cathedral to film Hogwarts, the media in England and the US did story after story about the neanderthal Christian church being up in arms and howling in protest. They claimed the uneducated rabble would descend on filming with pitchforks, flaming torches and drooling mouths.
In reality, one protester showed up. The media was so disappointed. Their boogeyman didn't cooperate.
