Your criticism seems to be due to the belief that, in a world where the only information on the internet could be treated as gospel, that would allow the experts opinion to come through easily. Unfortunately, that sets up the circumstance where the experts get granted much more exposure and trust than they necessarily deserve, and it inevitably gets subverted and abused.
I personally prefer the current system - treat all information as suspect until you can verify it. It leaves MUCH less room for exploitation than all of our other "trust by default" mediums.
