As you yourself state, this is a revolution but i found the same issues on this as you did. My fear is that by making it all an equal playing field those that invested the most into the platform, ie. whales, will not be rewarded sufficiently, thus pulling out their SP and crashing the price.
The stake based reward system, i really dont believe was ever created with the intention of creating a platform that rewards the highest quality content, but rather it was used as a way to attract investments. They would have gone with this route in the first place if that wasnt the case.

As much as i love 1account/1vote, equality and all that, that just wont work by itself. We need a somewhat of a hybrid system. I really believe if he flips the board this hard Steemit and all the other front-ends will crumble.
