You've managed to summarize exactly what happens to me whenever I try to explain my cryptocurrency investments to my family. For some reason, the KISS principle (Keep It Simple Stupid) is surprisingly difficult to apply to the world of crypto.
When I told my wife why I wanted to create a Steemit account, I just explained that it's like Facebook but you earn real money when people "like" your stuff. That was good enough for her.
Steemit is like a new model of car. If it works, most people will be happy and use it. But not everyone is interested in being a mechanic and knowing every little detail about what happens under the hood.
