The last Missing Piece of the steem puzzle

I remember when steem started a year ago, the insane inflation, the reward curve, the 2 year lock in period,etc...we've come a long way.
I want to thank the steem developers who have taken all the feedbacks from the community and have done an excellent job to prepare steem for primetime..
However there is still one fundamental problem in the way steem works in my opinion :

Wealthy individuals/organizations can silence anything on the platform and remove monetary rewards from anyone.
Some argue that steemit is censorship free because content cannot be deleted from the blockchain. It is to some extent but there are other ways you can censor content indirectly. One of which is to cut funding, basically the type of censorship youtube is involved in and that we are trying to prevent.

If you search 'censorship steemit' on youtube you will find dozens of users complain that their posts have effectively been demonetized and that steemit is no different from youtube. Censorship is alive and well on steemit, because your rewards havn't yet been taken away from you doesn't mean it isn't happening to others.

For the reasons outlined above I would like to propose a change to the downvote function. Currently it is stake based which means users's downvote power is relative to their steem power.
This makes the whole system very vulnerable and at the mercy of any wealthy entity willing to attack the network.

That's why I think the downvote function should be modified from stake based to consensus based. A post would need to have majority consensus against it for it to be downvoted. This is where reputation, account age,etc...comes in.
