Really good post that! My main worries are if Youtube suddenly decide they dont want to be associated with Steem then they won't allow the sharing of videos. And of course if any laws arre brought in to restrict cryptos. You say STEEM can't be censored but what if governments do heavily restrict it, then the vast majority of people wouldnt touch it and Steemit website couldn't survive. Personally some countries goverments may come in and ban it but I think as long as Steemit evolves and we keep ahead of the inevitable competition we will succeed in the long term.
