I'm not as paranoid as it sounds - just a curious idea.
If you're being watched by a specific organisation, national security or foreign power etc, my assumption would be that they would watch your router traffic / IP traffic after identifying you and your used networks in some clandestine fashion.
At this point, how would using things like Tor (and VPNs/other methods of "hiding") help? Because all your packets are being re-assembled at your end of things, would it not be obvious what they were, irrespective of the intriguing route they took around the world to reach you? Also, wouldn't your ISP have all this info too?
Not planning any illegal activities, just getting into networking and reading about TCP/IP and having thoughts that Tor only helps you remain undetected, not un-observable.
