The problem isn't any one cryptography scheme; the problem is trust. How do we build a trust framework that facilitates commerce on a wide scale while remaining truly secure? I don't think we can; so we give up a little bit of security for a whole lot of economic benefit. Without centralized, trusted gateways, it's not even clear that your communications are secure. They need to be centralized to make them easy to monitor and audit. With a distributed trust model, the compromise of one node can be catastrophic; all you're really doing is handing control of the trust network over to botnets. This is a really hard problem. I can't think of a better solution that would serve the same niche as our current one.
