I agree with most of what you say - I wrote about this 6 months ago and the inevitable pull of mathematics is leading Steem towards its final attractor: a coin creation protocol. The reward pool is just a coin-distribution mechanism; I don't think there is any need to break the macro-economics of the STEEM and SBD coins, but the micro-economics will not improve with EIP. Tellingly, @vandeberg has not posted his 3rd deep dive to explain to us what a fantastic idea 50% curation is; maybe he's done the maths - and it isn't.

The human interactions and rewards will develop within level 2 dapps. But each dapp needs to find the best way to tap into the Steem economic system as it currently exists - each token must have some value created in its relationship to STEEM.

I've been meaning to post on these issues - it isn't pretty but some things need to fall on deaf ears... might clean them out a bit.
