I can see your points. My feeling is that many of the "bad actors" will jump ship after hf21, if they haven't already. Granting curation powers to long time Steemit advocates will do good things for the platform, I know I would be delighted if even one of my followers suddenly became a dolphin.
When I first joined Steemit, I got a free temporary 200 sp delegation. It only took a few months before I bought my first Bitcoin, traded for Steem and powered up. The delegated sp did not discourage me from buying at all, it actually encouraged me to buy.
