What about techniques that obscure the source of information?

Whether it be something like Tor, or something like a distributed database, internet communication may require hardware and physical location of data, but there are ways to allow information transmission without being strongly reliant on a fixed physical source.

Also, this capability is not limited to the internet.

None of those technologies are bulletproof. Tor can be (and at least partially has been) compromised.
