Maybe an aspect not over emphasized about Bitcoin could be the educational one.
At anypoint of the speech you could say something like this: "Bitcoin helps you to stay away from the stuff you don't need to buy. Why? Because marketing usually likes to say 'Starting from a thousand dollars...' (or something like this)
If someone asks "Ok cool, but what about whit something I really need?" No problem, just use Bitcoin :)
What that means? It means that you give value at the mean of the exchange but also at goods & services you're gonna buy with it.
Less waste of money, less waste of production etc... more awarness
Ok, it could seems quite akward but it could works...or at least I hope
