If you think you've found any seriously gaping plot-hole, then I say you haven't seriously paid any close attention whatsover to the books/films. Wizardfolk live in society; adult wizards work to mantain said society, just like we all do in the real-world. You have genuinely missed the mark -- far from being presented as "childish fiction", as you put it, wizarding society is overwhelmingly believable in the way that it is exactly like ours with the added element of magic. There is a government (Ministry of Magic), law-making and administration of justice (Wizengamot), diplomacy and international cooperation (International Confederation of Wizards), education services (Hogwarts), research and scholarly pursuits (Arithmancers, Magizoologists, Herbologist, Potioneers, etc.), a health care system (St Mungo's Hospital), law enforcement (Aurors), trade and services (Diagon Alley), economy and banking (Gringotts Bank), press (The Daily Prophet), radio (Wizarding Wireless Network), transportation services (the Knight Bus), crafts (wandmakers, broom-makers, metal-charmers), arts and showbusiness (painters like Magenta Comstock, and famous singers like Celestina Warbeck, even bands like the Weird Sisters), sports (Quidditch), advocacy groups (S.P.E.W.), and I could just go on and on.
