I think your questions so far are good. And I love this article - https://vijayboyapati.medium.com/the-bullish-case-for-bitcoin-6ecc8bdecc1 - as a starter, before you recommend books to them.

That whole "encourage trade, not for saving" idea sounds fishy. A relation of mine was involved with one of these "community currency" deals. He gave much of his time, earning this community currency. It turns out that not many people ended up using it, and so he had a lot of it left, when it faded out. I remember one of the last things he could buy with it was a haircut, but only at a very low traffic time, like Tuesday morning or something. I think most of these efforts - because they can be printed endlessly - are even worse then fiat.

Consider checking out the history of previous efforts like this. I'd be surprised if ANY of them succeeded.
