Very well put! I had a post that went invisible within an hour or so of posting it due to a "dolphin" downvoting it, and the post contained only self produced content. This individual never spoke up about why they downvoted; it happened and my post was gone from the feed.
I have only ever downvoted one time, and it was for obvious plagiarism. I have the same stance that you do with this supposedly meant to be a free-market.
I view our posts as filing bug reports while this platform is in beta. I also view them as constructive criticism. I believe this platform is absolutely amazing and has a strong possibility of altering the global paradigm as we know it. Yet that doesn't mean I don't think it could be better. Eliminating as much hostility as possible I believe is a very desirable goal.
