Oh god, I agree with the risk associated with a Single Point of Failure -- there's just too much relying on things running as efficiently as possible to take that risk. I think JKR mentioned there were 3000 wizards in Britain, which to me seems a bit small because she also said there were "thousands" of students in Hogwarts, plus the wizarding society seems plenty robust to me.
