All though interesting, I don't believe block reward voting to be useful as everyone regardless of large or small stake will vote for the lowest possible block reward to increase the value of any coins mined.
Increasing the coin supply does not increase the value. Likewise reducing the block reward increases the scarcity (value).
Why would anyone vote otherwise?
This is an interesting post, and I think it highlights why block reward voting is so interesting.
As you say, there is a really strong argument for miners with _any_ stake to vote for 0 block reward.
On the other hand, other users seem to think the opposite.
I think that the voting for reward thing isn't going to work as you think it will... I don't see any reason for a miner to vote for a lower reward.
As ymer says, there's still a huge incentive for miners to vote for the maximum reward. We think this is especially true for miners without a stake or with a small stakes.
Thus, already we have two users with two very different (actually opposing) ideas for how to vote.
We think that the way these forces play out will be very interesting and could give rise to some surprising results!
