I think we agree.
To be clear any form of vote "trading" where people can directly purchase votes which give them more money than they spend, seems indisinguishable from a scam to me. Perhaps my economics are not strong enough to see how it isn't a scam, but, then again, when it smells like a duck... IDK how steem can survive if people can "buy money" in such a direct way.
If you mean that there are other forms of vote trading / organization, which are inevitable and ok, and may generate substantial profits for some, I agree that would be fine and good.
