I don't often upvote, but I've many times thought the same. What you you wrote is spot on, therefore I gave you my upvote.

Regarding the matter, I think it's a fair comparison. Sure, there's some virtuality to data traffic as opposed to physical shipping for example, but there's always a physical dimension there as well. Free markets and competition never fully works where there's limited resources (in this case, the space and availability of network infrastructure). In addition, physical infrastructure can be blocked by competitors in many different ways, hindering new players trying to compete.
