"...splitting reward pool for passive and active investors, two groups of people, where other just wants their wealth and other who care about Steem for long term and want to curate?"

SMTs will do this, with Oracles, and Communities creating those two filters - and myriad others.

Focus. It's possible that the rigors of channeling Steem and also delivering the many UX that Steem makes possible are beyond a single organization. In fact, I am certain it is.

Given that reality, it's necessary to empower, rather than disestablish individual enterprises, however unsavory they may be, because only a free market might moon Steem. Too rigid control over UX, including Steemit, is a distraction and reduces the potential of Steem to serve all markets.
