One hand if ALL papers were forced to be published without authors then all shity papers would dissapear (which is 80% of current lot), there will be no "publish or perish" and lot of eliteness and egoism will go away.

On other hand, how do you decide if person is worth talking to? worth collaborating? worth giving tenure? The problem exacerbates when supply side dominates many magnitudes over demand side. This is precisely why we as human always keep establishing trust relationships that allows us to filter out signals from noise. You monitor writings of people you know have produced stuff on interests, not every random thing out there.
