What new "tollbooths and gatekeepers" is he talking about? If I wanted to start an online store or search engine today, who would I be paying?

I'm certainly not saying I agree with this wholeheartedly, but I think his point is that you wouldn't get very far without (my examples here) a Facebook and Twitter presence, and an iPhone and Android app.

Search engine: You'd be paying for traffic. Google does it. Bing does it. You'd have to do is. P.S. Good luck with that one, you're going to need it.

Online store: You'd be paying for adwords, probably.
