"My only problem with your idea is that it might kill the motive to buy steem and or cause people to sell."

Who is buying Steem that the promotion of capital gains might discourage?

Markets predate writing. Capital gains has proved to encourage investment and positive social development. That principle is sound, understandable, and proved since prehistory. I do not fear it won't work.

As to my sense of ethics, markets do not have ethics. It is not my sense of ethics that caused HRC to buy the nomination from the DNC, nor the lack of it that caused the ethical members of the market to vote against her. The market appears ethical because the individuals that comprise it are ethical, and the market for Steem reveals that my ethics appear to be the same as those in the market, because demand for Steem is not increased by financial corruption manipulating rewards comprises.

I don't want Steem to fail in the marketplace because it has some great features the market is yearning for, that the market values very highly. That it is failing in the marketplace despite these great features shows that it is being broken by very bad practices, equivalent to buying votes in a market that utterly reviles such corruption, and that is what I want to see change.
