There's a multitude of reasoning or rather "speculations" on the impact this hardfork is supposed to make.

From what I understand the gist of the EIP is aimed at making the staking of steem-power and actively curation with it more attractive while also nudging "abusive" voting-behavior to concentrate on single pieces of content for the best efficiency rather than splitting it over many low rewarded content pieces that will easily go unnoticed. Which is where the "free-downvotes" would come into play?!

I don't think we can compare the reward-pool mechanism with the model of taxation at all, but I certainly feel a bit hit over the head from up above by these changes, too.

How all these speculations play out eventually remains to be seen. This blockchain idea and steem even more so is one big social experiment after all.

We're in for an exciting ride. At least drama will keep things entertaining ;)
