You want drama? Turn it around; do away with curation rewards. Only those who actually like content and are involved will vote, because there would be no financial motivation for voting. No more easy money without creating content. Motives for voting will change for the better, Steemit will lose much of its scammy image, bot owners will panic, delegators will jump off buildings.
Nobody would buy or hold Steem anymore, you say? Well, people buy and hold other cryptocurrencies without any hope of interest or curation rewards, so why would Steem be an exception?
... or any other story you would want to put behind it; you can probably make up a better one than I can.
But drama? Oh yes.
