My interest in the internet is nothing more than testing my abilities as a penetration tester, with little or no knowledge of the victim. If you think you have thought of everything, I will create that which you never thought of.. just to prove it can be done.
You sound like you focus on physical security more than network security.
First, create laws requiring interception of all traffic at the ISP level.
Second, lets give it a fictional name, like 'No Shitty Attacks' or NSA for short.
Place 'NSA Killbox' between ISP and the world. Switch to record mode.
This means A box between YOUR isp, and the rest of the world. Nothing you can do about this.
There is a box between most user's ISP and their network already: home routers that tend to have back-doors the NSA probably knows about. They may be reluctant to exploit these in a readily detectable manner for fear of the back-door being discovered.
When it's decided bitcoin is a threat to the security of any MAJOR country, they can force the isp to re-route p2p traffic to a dns dead end. At this point they can be clear and say, you want passed here, your paying for it.. This is how to tax bitcoin.
Or I could just look at the block chain for address's, write any address found there into my fresh wallet, and take all, using that dns redirect..
Here you don't appear to understand how bitcoin works. Bitcoin does not strictly rely on all users having direct Internet access. You can distribute the block chain and transactions by modem or mail links.
It will take a while for the super-powers to attack Bitcoin directly due to its strategic importance. If one super power decides to unilaterally attack the network, they risk sparking a new arms race from competing super powers trying to defend it.
Edit: a dns dead-end is easy to work-around.
1. Yes I focus on physical security, and leave the programming to those that can. As long as there is someone who can interpret my words into a script that can run, I'm happy. I know of around 10 decent programmers who can do this. It's better someone with my ability to 'see' the possible way around keeps this to a minimum.
2. Tis is not the network I was refering to, the network I was refering to is the one the cmts connect's you to for you to get the net. A short way.. connect to the cmts, the cmts connects to THE box, then you are forwarded to the net. This was mostly first used in early tv, the 3 minute gap between live broadcast and transmission to the masses.. the delay required to manipulate.. ANYTHING..
And for your edit.. yes, and how to is already mentioned? I did'nt link the 2 intentionally
