I will use my network for what I want my network to do for me. There are

I want with it and not be a bad actor.

So by your logic, a bank's internal network used to drive its ATM 
machines is not neutral because one cannot use that network for global 
IP Transit?

Well, yes and no.

While it is true that one of the biggest problems of the Internet is the 
last mile, it is vital to not be forced into the mistake of 
classification. For some operators, the "last mile" is the biggest cost. 
For other networks, the "backbone" is the biggest cost.

You can't tell me that US$700 million being spent to build a submarine 
cable around a continent is something to scoff at.

For me, I don't want to hold myself back by classifying "access", 
"backbone", "metro", e.t.c. Your business model will determine what is 
costly to you, and what isn't.

Again, you are trying to keep the old Internet (and the classic 
telephone company model) alive in 2021. That is not how operators work 
anymore. There are networks that have neither a "backbone" nor an 
"access network" that do very well, and don't cause anyone else pain, 
because they are clear in what their model is.

Okay, so by your logic, "access providers" should pay CDN's for peering, 
because the CDN's have spent millions building submarine cables and data 
centres around the world to bring their service to the access providers. 
After all, why give the access providers a free ride either?

In case it's not clear, that last paragraph was sarcastic. It's 2021 - 
long distance, access, backbone, metro, e.t.c. Those are boxes that 
don't exist anymore. Let's not refuse the advancement of the model 
because we can't find a way to make it fit in our old box.
