Yes I wondered whether this complexity is a factor of enterprise design: Each engineer is responsible for a subsystem, ending up with x^n pieces, whereas the counterfeit one took 1 or 2 engineers.
There are two sources of complexity in the charger:
PFC and efficient resonant converter, which is to be expected of high-quality charger.
The whole magsafe handshaking mechanism, which looks like an afterthought to solve reliability problems caused by arcing on the pins, that also got used to block counterfeiters.
