Right. But I doubt that anyone shifting that much traffic just buys 100G internet service to a certain location.
If you push out that much you might make use of CDNs, if you consume that much Netflix/Google I guess you meet their criteria and the CDNs talk to you (and place their edge servers in your network).
True enough. The distinction really comes down to want and need 100G. If you need 100G, you have options and peering is on the table. If you just want 100G, like Rocket Fiber with their 19 buildings, not so much.
As to buying transit on a 100G port, obscene is perhaps a bit harsh. Transit cost goes down significantly with volume and there rarely is a need to commit to a full 100G port. In any case price per Mbps is going to be in cents, not dollars.
