In addition they probably are aware that the inflation rate will decrease over time to .95% so as the Steem Based Economy matures and slows, the money supply growth will slow as well.

That's the point - I bet that most of them are not aware of this fact because this information is not exposed properly. Which is quite strange, as for most people (especially the skeptical ones) this is absolutely a crucial piece of information.

The most powerful marketing strategy we have is to leverage the popularity of Bitcoin and draw analogy between Steem economic model and Bitcoin. Basically it goes like this: "If Bitcoin makes sense, so does Steem". But to be able to do that you cannot leave out the decreasing inflation aspect, as this is definitely the most convincing argument that (for most people) separates Bitcoin from a Ponzi scheme. If you leave it out, Steem becomes incomparable to Bitcoin.

I'm not arguing that this assumption is true in economic terms. Instead, I'm just arguing that this is how people perceive it. And perception matters a great deal. And it matters both for investors and actual users - people don't want to participate in something which they cannot grasp conceptually. Who would devote their time and commitment to something that they think can collapse any moment?

In the video you only say this:

Like most blockchain protocols, the Steem Protocol creates money out of thin air, called Steem Tokens. It creates these tokens at a rate of 9.5% a year.

Otherwise, this video is great. You have a real talent to explain complex things in a very clear manner.
