nice hints !
i totally agree with you about some necessary improvements !
We need tested and working blockchain consensus structures to realize stuff like this.
The concepts of DAOs will presumably create solutions for these kind of organizations and will even invent unknown usecases. 
But i would argue that we need a working stable coin in the first place !
"Regulated" proportionalities of valuations are necessary for most business and trading.  
I plan on making an updated post about the MAKER DAO project. (which offers an ethereum based stablecoin called DAI)
Which could be a great solution for a lot of Applications and Projects which need stability in the first place while using cryptocurrencies.

+ (imho Steemit is a great governance experiment, which lessons will help to improve community features for DAO business structures like shared economies)
