I strongly disagree. If this were true, there would be no market for
MPLS service: folks would simply buy Internet service and run VPNs.

If you take my packets off at the first hop and deliver them to a 3rd
party provider, I can buy service from that 3rd party with as many IP
addresses as I want, I can buy service with BGP routing, I can buy
non-Internet services and I can buy bandwidth-hungry services that
aren't cost effective when they take a trip through the Internet
backbone.

Even if the cost for the unbundled L2 circuit was *identical* to the
cost of the bundled Internet circuit it would enable a huge range of
niche products that aren't practical now.
