> You don't need advertising to make money if what you're doing is valuable.

Not necessarily. There is a threshold of value that must be met to make people pay directly for it. For example I run a niche site that gets 5K uniques each month - clearly I'm providing some value - but I doubt that what I provide is enough to make people pay me directly. Ads are the most effective way of solve that problem: reward content producers that can't meet that threshold but still add some value.
