Its difficult enough for people in the money space to thoroughly understand Bitcoin (we all say we understand it, but do we really?).
For a common person, its an overkill. Its like trying to explain the concept of TCP/IP, Networking, Routing, the Internet for someone who wants to use email. Overkill.
I'm an ordinary person, and in my opinion it is not excessive if we will try to learn it well.
What you say's no different with making a website, I myself look at it like a Pokemon Android GAME we will not know where bitcoin location's when mined however when we find and retrieve it then the number of points increases.
