That one's easy, actually.  There's an economic model underlying
end-to-end networking that's trivially but completely incompatible
with the way capitalism works - there's not really a good way to
describe what's mine and what's not mine, how to account for
resource utilization and charge for it, etc.  I do think that
it can be mitigated and that figuring out a business model that
accommodates policy at the edge is a really interesting project
(for somebody else), but until that happens the people who deploy
networks are going to continue to take the easy-to-understand
route towards making the edges of their networks distinct and
manageable.
