However, what this also means is in the almost two years since that time, Steem has added 15 million dollars worth of Steem more into people's accounts. That is a fair amount to be spread by a startup company that hasn't completed its third year of operation and most people haven't bought in, isn't it? I actually find this quite incredible.

This is what stumps most people. They will ask where the money comes from. Investors. Same as the money Quora paid its bills with for quite some time before it finished developing revenue streams from all the traffic. Except that in case of Steem apps, the money goes to the users, out of whom those with the most stake tend to be developers and witnesses, but the majority of whom are content creators. If you are a content creator, know about Steem and understand what it is, have a blog you're trying to monetize on WordPress and refuse to set up SteemPress and a Steem account, then I'm forced to conclude that there is something seriously wrong with you.
