I don't believe that all users do, but I believe that a significant part of the stakeholders which have significant interest in the platform will try to make a responsible decision for the platform to avoid bad content.
Having, as proposed, a pool similar to 10-25% is not enough for significant abuse (as discussed in the post) but allows the community to action more easily.
If the effect it is going to have is going to be more positive than negative is going to be something we will see.
We'd be stupid to not try though.
