Thank you for your explanation such that an ordinary minnow is able to understand you.
Like you rightly pointed out, minning will worsen the cry of minnows and people who may not have the technicalities to mine the tokens.
If you consider that many ordinary people are in steemit and not other platform, it will tell you that steemit is able to achieve this because it involves what everyone can do which is writing.
Bringing mining into any aspect of steemit will be counterproductive.
