Re: Confluence
If you've killed ISPs your router will become invisible as it's your ISP who connects you to the net. Your will not only have to keep your ISP, you'll also have to persuade them to give it a static address or add a DDNS provider to your list of dependencies.
Using the phone is an even bigger problem. You no longer have an individual identity, your phone does. Lose it or get it nicked and you can start looking for a cardboard box to live in.
