I am fine with encryption, but there should be a legal process that can stop the violation of laws such as by disconnecting nodes that violate laws or preventing linking to nodes that violate laws.
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.
