I understand why authors would not want to take a cut from their allocation from the inflation but please keep in mind that the monetary value comes from those buying steem not the authors. Also, taking a cut from the witnesses is not a good idea.
This might be hard to hear for some people but the blockchain can survive without authors but not without investors (steem power holders) or whithout witnesses (without them there is no blockchain).
Besides authors would still receive a big chunk of the inflation so think about this.
Creators would only receive any chunk of inflation if they actually receive rewards. Some proposals extant would cut author rewards by 2/3. What do you think this would do to Steem? Retention is already below 10%. Cutting most of the rewards authors might generate would not improve this.
I think you are not recognizing that creators of content are the only source of value for Steem. No content, no reason to invest, no reason to curate, nada. Zip. Steem could not exist absent content, and decreasing author rewards will decrease further account generation and retention.
I agree that content generation has it's value via the attraction of more people to the network. However social media apps built on top of the chain serve mostly as fancy faucets for content creators.
The Steem blockchain can be much more than blogging and social apps (steemmonsters is an example that comes to mind). I just think that giving more than 50% of the inflation to the group that least contributes to creating direct demand for the coin is not sustainable in the long run. To me around 40% would be a good number.
The current 75/25 distribution between authors and curators is mis-aligned. The later group takes all the risk of locking up their investment and should receive a higher portion of the reward pool.
Most current users are not aware that it used to be 50/50. The proposal from blocktrades would leave the distribution of the reward pool at around 64/36. Overall authors would receive 46% of the total inflation instead of the 55%-56% that they get today.
