Now I seem to have got time enough to fully agree with you.  

The next facebook will start in a low-price datacenter. These
facilities did not exist as products before, and it can be argued that
the access/content separation does drive that market -- as long as I
had working Internet (as opposed to access class "Internet" ) at home,
I had no use for a colo.

Still, the centralization of content into a few networks does raise a
number of issues -- mostly regarding stability. Do note here that
several factors negatively impact stability, be they technical,
economical or legal. Peter Löthberg long ago advocated a network
interconnection model that was pretty local (and I believe he still
does). Peer often and everywhere.  That would take care of packets
getting through (as long as we all have unique addresses to point at;
v6 fixes this) The services that take the Net from being a graph
problem for nerds with BGP CLI access into what it has become need to
undergo similar fine-graining to keep up.

Oh, sorry, got carried away.
