I think that there will be plenty of innovation to get around the CLRC issues for smaller payouts and comments. These will mostly rely on aggregation techniques, or as you suggest, various forms of vote-selling.
It's a pain though. The CLRC will just bring additional complexity in return for (as far as I'm concerned) no obvious tangible benefit. The "divisible account" issue could be solved through data analysis and downvotes instead.
Downvotes are still unincentivized and rely on altruism and volunteer work for effort. It is important not to allow that to be attacked by ramping up the necessary effort. Keeping rewards concentrated even if it happens via aggregation techniques as you suggest is necessary to manage the workload required for downvotes. If those aggregation techniques are used in an exploitative manner, they can much more easily be countered with downvotes than 100k or 500k comments scattered all over the place.
upvoted due to troll downvote, not that i necessarily agree with your comment, just wanted that out there.
