This model works for buying advertising space on ESPN, or in a print magazine, but not on the internet. Economies of scale, need for targeting, the inability to force unskippable 5-minute-long streams of ads on users...

There's a reason why everybody uses ad networks.

I’ve done all this myself before – even when running a small Let’s Play site with a few friends we negotiated with publishers directly for advertising, and managed to get quite good deals.

I’m not sure why you think this is so complicated or impossible.
