Re: How long...
"Pretty soon SOMEONE will propose the redo the Internet from the beginning: this time with full attestation at all points; no more anonymity."
I could live with that. The bad governments can already tell (if they want to) if you are connecting to an end-point that lies outside their control, so today's VPN fans are already subject to the sort of traffic analysis that such a proposal would allow. On the other hand, a reliable (or even semi-reliable) method of determining where content had come from would make your average spam filter about a billion times more accurate.
Anonymity on the internet is like guns in real life. If you have it, you are either already known to the government and doing it within local law, or you are outside the law and they'll come down on you like a ton of shit if they ever find out.
The solution is to fix your government so that they aren't a bunch of control freaks. Merely using technological band-aids to make it hard for them will just make them angry control freaks.
