2. The Internet cannot "route around" de-peering
I know everyone believes "the Internet routes around failures".
While
occasionally true, it does not hold in this case.  To "route
around" the
"failure" would require transit.  See item #1.

The internet "routes around" technical failures, not political ones.

If two transit free networks have a technical failure which disables
all peering between them, the Internet cannot route around it.

Sure it can. The traffic just flows through any of the providers that still
have reliable high-bandwidth connectivity to both of those providers.

Unless, of course, a pre-existing political failure prohibits this traffic.
The Internet can't route around that political failure.

From a technical standpoint, the Internet is always suffering from multiple
political failures. This leaves it vulnerable to small technical failures it
could otherwise route around.
