So my Sprint EVDO (hypothetical, not real) can't get to the DSL line I've
got through $cheap-Cogent-bandwidth-DSL-provider (also hypothetical, not 
something I have, but I know of such a provider.  Given they're not at
fault in this dispute, I will not name them.)  So what you're saying is
that I'm expected ... to go get myself some space in a data center so that
I can buy some more Internet connectivity in the data center so that I can
bounce my VPN connection from my laptop to my home office via the data
center?

That's insane.

Let's try to remember that the Internet isn't the sort of "content provider"
and "end-user" thing you're pretending it is.  This model is loosely true
for some large percentage of traffic, but it is by no means the only usage
model.

Further, why should content networks be taxed extra in the manner you 
suggest?

Are you willing to mandate that customers in Sprint and Cogent colocation 
centers must be offered reasonable pricing on connections to alternate 
providers?

You really don't want all your content providers multihoming in any case,
there are far too many of them, and encouraging each one to solve its own
connectivity problem will result in an explosion of the routing table.
