No. Where is the "consensus ledger?"
This is actually quite relevant to the Lightning Network. In the "bitcoin=internet" analogy, the core broadcast network (the blockchain) is equivalent to the Internet layer (IPv4)--the layer that routes most internet traffic. HTTP is part of the Application layer, which is a layer built on top of IPv4 due to IPv4's limited capacities for proper data delivery, sequencing and integrity.
i think the point was that the internet was scaled by adding layers and soft forking
the TCP/IP layer has stay the same, but with the HTTP layer thrown onto and later another layer ( JS / CSS / Flash etc. )
we have managed to get scale the internet without HardForking the underlying protocol TCP/IP
its an analogy that isn't perfect but isn't have bad...
... coming around to the 'right' way of thinking I see?
You need to throw in possibilities for UDP/IP and streaming-like analogies also, they move a LOT of traffic. Tiered-routing, NAT, IPSec, VPNs and others all add to the zoo of layered data solutions all based on IP but expanding its utility, capacity, effectiveness, etc.
