Honestly, I love this post, I have been thinking about this lately, because I have discovered that majority of steemit users are so obsessed with the rewards and not even the added value of platform and that is obviously why someone picks offense when downvoted.
But in the other hand I think stake based voting may bring up injustice or rather politicize steemit in the later future when it becomes populated where major stakeholder decides who's gonna get paid or not regardless of the quality of your content. You know what we call "POWER ROITING" may occur.
