It seems that the real complication is the Comcast has such a huge marketshare that they don't need to be competitive on peering. Whereas if they had real competition, then subscribers would drop Comcast and go with an ISP that peers better.
Yes, provided you deliver it to the designated IX for my location and pay whatever applicable meet-me-room fees. Realistically only CDNs are going to do that for the O(100s) of locations in the country.
The alternative is to "negotiate" with Comcast. Since your BATNA is losing access to a huge fraction of Internet subscribers, Comcast is going to calculate your business's profit per megabyte and demand 90% of that. They know what Netflix costs. They know how much bandwidth the average Netflix customer uses.
A peer connection in the same city as the subscriber is literally the cheapest traffic for Comcast's network to handle. If their rates don't cover bandwidth to that, they should raise their rates.
And buying transit is even cooler! Let's do this, you go signup for 1Mbps from Comcast, then I'll put a server on my own ISP and you can go force Comcast to buy from me. I charge $1000/Kbps.
The Comcast/Netflix intentional congestion thing actually happened and caused actual harm, so I'm not sure why you're responding with trolling.
