There was a time when if you wanted to transport yourself or your goods across say Europe or China, you needed to hire mercenaries and they would protect your business from bandits on the way.

At various times (Mongols, US Navy vs pirates etc) governments stepped in and provided that protection (for a lesser price) and trade grew.

I'm not too sure how governments can provide protection in the online realm. Perhaps by providing minimal standards of security? (I know the standards exists but enforcing them?)

However, now my iPhone is FBI-resistant, and public keys are fairly easy to share, it seems that secure peer to peer communication is feasible.

So the shape of a more secure, bandit free internet is clearer - hardened mobile devices, and much much stricter standards that are enforced, but it seems an odd new world.
