1) You can have an encrypted connection between two jurisdictions that have different laws, but then anyone can route around censorship because you don't know if they're discussing geopolitics or distributing DeCSS.
2) You can't have an encrypted connection between two jurisdictions that have different laws, which is >99% of all connections because even different cities have different laws, which is an Orwellian panopticon and the destruction of all privacy.
I'm going to have to insist we stick with the first one.
Are you prepared to be held accountable for breaking the laws of repressed countries that sentence people to death for leaving a religion or insulting authority?
I assume not, but then it's an arbitrary game of whos laws and when. The only logical continuation would be if we had a standard of law worldwide, but that's a separate problem in itself and not anywhere near reality today.
If people in your jurisdiction can make a secure connection to it, e.g. to get the 98% of the content they have which is lawful in your jurisdiction, then they can also get the content you were trying to ban because you can't tell which one they're doing. Preventing this is all or nothing: Either they can connect to the server that isn't subject to your laws, or they can't. And the latter is heinous and tyrannical.
You can only issue takedowns in relation with material that you have copyright over. At least one of these sites I know for a fact routinely scrubs FAKKU licensed content, and abides by takedown requests.
This seems like turtles all the way down.
