I take your point on the BTC plunge, that is likely the reason Steem dropped as much as it did. The notion of abusers is the questionable one. The blockchain affords people special privileges based on their investment in Steem. When you prevent people from exercising SP to their benefit, you give them a reason to dump to the market. The big question is, which is more valuable; Retaining them as stakeholders and allowing them to draw the rewards that the coded rate-limit voting allows for, or send them packing in hopes that someone more virtuous will take their place? I know your answer to this question, and I'm only guessing that it's predicated on the idea that these folks are replaceable. So surely you've found a way to pitch the virtuous capitalist, yes? You can chase away "the profiteers" all day long, but if they're not replaced, the platform loses investors, and as selling happens prices trend down.
