"...vote-selling is in fact a community destroyer and not a community builder..."

This is a glimpse of the basic principle at stake. Society isn't an economy, but much, much more. Reducing one's participation in society to mere economics degrades society. This isn't just a principle that affects Steemit, and clearly is the basis for much that is, and has long been, wrong in the world. Was it Jesus that said 'The love of money is the root of all evil'?

Society is about people engaging and building relationships. Automated voting of any kind, and particularly when conflated with stake-weighting, degrade society, and directly counter that purpose.

Potential solutions are coming, in the form of SOC (SMTs, Oracles, and Communities). Soon there will be examples of all kinds of communities that potentiate rewarding participants in various ways, and there will be some that demonstrate exactly how stake-weighting and botvotes are harmful, and how much more powerful society is than mere economy.
