Advertisers are more willing to spend money to promote content than an individual is willing to do the same...

Having multiple different distribution channels can solve that problem. Advertisers cannot monopolize all distribution channels simultaneously because of the costs involved (it would be like someone trying to buy the whole economy).

Using a real identity doesn't fix that problem either though: advertisers just pay real people in India to do ID checks.
