I'm not sure I understand your perspective here, or what you're defining
as an "internal network." I can't imagine a future where every local
operator decides to open up every host on their network to the entire
Internet. There will always be a need for virtual networks between
remote offices of the same company for example, or between 2 companies
that have a joint project that requires sharing data.

There isn't going to be a "return to end-to-end." Users don't want it,
and it almost certainly is not a good idea even if they did.
