The majority of the economic incentives won't be that hard to sidestep with the proper dapps in place.

The reward curve is easily defeated.
Curation is easily defeated.
The flag pool is self-defeating.

The only thing that can't be avoided really is the siphon that funds development. Arguably, it would be hard for this to yield negative results even if it was extremely corrupted, so no worries there either.

At the end of the day Steem will learn to incorporate the smartest economic plan or be abandoned for better politics on a side chain. Of course this will take years and years to come to fruition.
