The problem with a universal dividend (or i would call what you propose "free steem" - since a dividend would be proportional to ownership) is fake accounts.

My proposal is that we let people opt out of the reward pool and receive what they would have gotten if they had 100% self-upvoted, i call that a dividend for lack of a better term.

We need to let people be "steem owners" without forcing those owners to pick the content that everyone on steemit sees.
