Steem as dapp blockchain and steem token only as a utility token is the only option. SMT for rewards.
I can easily see this thing working. We're early in the game. You're making mistake not to try to get as many steem as possible. In five years no one will know or care how you got yours. Buy, earn, spam or even steal.
You'll either have them or not.

Oldtimer, Justine, Acidio, Bernie or Ned. We'll all be dust when big boys join the party.
If that ever happens. I definitely count on that but you never know.
Right now I would bet on 60/40.
