Does it need to be? Most people don't know anything about the underpinnings of the bank and credit card systems. I talk about btc as pseudonymous digital cash first (and the tradeoffs of consumer/producer benefits that entails), mention its capability for more (escrow, 'programmable money', store of value, signatures...) next, and give my best go at explaining what I know of the more complicated details of the implementation only to people really interested. It's fun to try metaphors (and there are a lot, even just around asymmetric encryption) for those without the tech background but I don't think it's very fruitful.
