In order to do that you'll need to discourage profiteering and downvotes. The EIP does the opposite. Improving retention will depend on rising Steem price, as our short history shows.

Every time the ability of stakeholders to extract profits from rewards has been increased, the market cap of Steem has decreased. We've slid about 30 places on CMC in the two years I've been here.

Wanna stop that slide? That's what you'll need to do to make Steem a household name and currency. To do that, you're going to have to encourage SMALL stakeholders to use it, and allowing substantial stakeholders to censor, downvote, and outbid them for rewards doled out by bots does the exact opposite.
