Direct democracy invalidates Representing anything. It's the choices of the majority, that's all, hence why democracy is always the majority voting to eat the minority for dinner.
The problem is with saying that the voice of One individual equates to anything remotely representing the community on the other hand, such as Sneak's Freedom of Expressing his opinion of a topic, it actually doesn't say ANYTHING about: Steem, Steemit Inc, The Community, Vaccines, or anything other than the fact that it's his opinion. Free Speech friendly indeed, and I should know I have taken down troll after troll of people purveying vaccines as even mildly ok, and it's clearly transparent while nothing and nobody can stop you from speaking your mind on here.
Equating weighted voting to democracy would be equating democracy to your vote counts only if you have 50k or more, and that's not an opinion but the begrudging reality of Vests vs One Vote One Voter Democracy.
