Some food for thought on what's driving a shift in globalization and what it becomes:

Big nation-state militaries => D2, no funding => corporate militaries and local militias.

Transportation intensive trade => D2, Peak Oil => Virtual trade and local production.

Nation-state => illegitimacy, insolvency, loss of control => Resilient Communities and Hollow states.

Contractual legal system => extreme corruption, unsupportable overhead, trumped by violence => Reputation (a low overhead system that scales) and fear of reprisal.

Global flows of people (immigration, tourism, etc.) => D2, pandemics, terrorism, repression, superbugs => People stay local and interact virtually.

Global financial system => corruption, instability => alternative trading systems (outside existing global systems), local and network currencies (virtual).

Intellectual property fueled by legalistic monopolies => low innovation rates, stagnation, inability to police => open source ideas fueled by reputation enhancement and services.
