Who is the receiver? Me, or my ISP?
You are the receiver. Your ISP is a carrier. You elect to connect to private networks, who may charge subscription fees of you. For use of the ISP's network, those same private network owners may pay for their provisioned capacity.
...what happens if my ISP decides - of its own free will or because Disney/Government forced it to - to deny anonymous inbound traffic? I don't have any choice of ISPs where I live, and of course they too would be forced to obey such laws.
This is possible, sure. Just as, today, the same lobbying group could attempt to force the government to mandate that your ISP sniff your every packet to detect that you're pirating Steamboat Willie. However, bear in mind that the goal is to add an economic incentive to the ISP to fight restrictions. The ISP wants to sell services to as many private network providers as possible because they are being paid for the reserved capacity. When the copyright cartel meets the ISP lobby in Congress, there's at least a chance that things could improve. As it stands, the only ISP incentive to fight it is the cost of the monitoring equipment, and I'm sure the copyright cartel would be thrilled to provide it to them, along with their own custom software....
...the rest of us are not allowed to keep our own anonymous network, because anonymity is a threat to those in power by making monitoring people harder. Please cease researching growth hormones for Big Brother, it's huge enough already.
Either I have not explained things adequately or you have misunderstood. The goal is to enable disruptive, innovative network technologies which cannot currently be deployed because they might conflict with the existing technologies. (For a particularly disruptive example, look at Decongestion Control [PDF].) There's no desire to block existing technologies, and I'd fully expect the existing Internet to continue alongside the new networks. Retaining the existing Internet is a primary goal of the research thrust, and I'd reject as unworkable any new architecture that didn't enable it.
Really, the most undesirable thing about the model is that it enables a lot more nickel-and-diming from the ISPs and the network providers. You might pay a base fee for ISP connectivity, followed by an additional fee for access to the base Internet, then you pay a fee to connect to the SpamFreeEmailNetwork, and so forth ad nauseum. But at least you only need to pay for the services you use, and I could see package deals (analogous to cable channel bundles) becoming a selling point, too.
