Having people gaming that system not only cause sell pressure, but have other potential side effects as well.

Selling endorsements (upvotes) is a primary use-case for steem. Advertising is the primary source of funding for facebook, youtube, and google.

Punishing people for boosting their visibility is 100% counter-productive!!!

Take the whale that has been self-voting for over a year with his 1.4M SP. He was stopped by a collective effort. At one point, he was raking in 2% of the daily rewards. People need to be able to disagree with rewards.

What moral theory are you defending??

If someone wants to buy 1.4 million steem and power it up, WE NEED TO KISS THAT INVESTOR'S ROTTEN STINKY FEET!!

WE NEED MARKET-CAP. And you don't boost market-cap by CHASING AWAY INVESTORS WILLING TO BUY 1.4 MILLION STEEM AND LOCK IT AWAY (power it up)!!!
