No one made that assertion, as far as I can recall, in the current discussion, although I have seen intimations of such.
But as far as I know, it has not been tested, examined or modeled in any depth. I wish it could be.

Of course not. But if various factors conspire, as you say, to "force" people to do that, it's precisely the kind of trade-off that needs to be understood better. As economic analyst, I am not immediately interested in whether that's a the ideal situation for the Internet. I am interested in
a) if it is happening
b) what economic incentives are making it happen and sustaining it
c) what externalities (negative or otherwise) it imposes on the rest of the Internet
There are people on this list who seem to be deeply threatened by the fact that someone is merely asking these kinds of questions. I am completely puzzled by this.
