No, I am sorry to say that your assumptions are not true. I have started working on the Internet in 1998, and I worked on core TCP/IP protocols and Ethernet device drivers, which is what drives today most of the corporate networks.
1)Your assumption that one has to petition corporations and governments and eventually suck it up is totally wrong. It's not only Tor. If you want to safeguard your own communications, you could setup an SSH tunnel between two BSD/Linux hosts and as long as you (or somebody you trust) can control these hosts, governments will have hard time to break you in the middle (I hope you do not start with the theories that encryption algorithms are tapped. They are not, and you are free to choose, and you have the source code to prove that). No corporation can stop you from doing that to establish who you wish to talk to, when and how. They might make it difficult, but not impossible and certainly within the feasibility of a capable IT person(s).
2)On the other hand, the assumption that the guy who sits on NSA/GCHQ has the will to listen to your personal communications one morning is also wrong. If you are an intelligence analyst, you are looking for needles in a haystack and you have specific problems to solve. Yes, there is data mining. Yes, there are ways to tap into your personal communications. Yes, you could be a bystander and accidentally tapped into in an attempt to locate someone, but this is less probable than you being the victim of a phishing/zero day exploit of some bad arse that wants your machine for a botnet, or is after your bank account, etc.
3)If you have something to hide (aka you are someone's enemy), the problem is not the technology, but the position you bring yourself into. Have the most advanced protection, they will get you, not by means of technology, but also by other means. If you have nothing to hide and you are just concerned that they might listen to you, take your measures. As I said in 1), technologies do exist to ensure that you keep whatever you wish to keep amongst few people (family, partners).
Personally, I have nothing to hide. If NSA/GCHQ want to listen to how I talk to my partners (sometimes swearing into IT problems) or what I ate in the evening, or when I need to go to the toilet, or what I order for pizza, they are welcome. Because, first I do not have a troubling position and secondly, when I talk to my family for something serious, I won't do it via the phone or facebook or twitter. I will do it in person.
So, I wish that people would spare all that crap about NSA/GCHQ listening to them. This is paranoia in the same way that you expect from Snowden and Assange to tell you that Governments around the world are playing dirty. Do you really need them to figure out that they do this? Do you really think that the big news networks are really concerned with your privacy, or rather with the advert they are going to air just before they give the latest on snowden's Moscow hotel/airport status?
Enough with this s***! Sorry, I would rather be cynical and pragmatic rather than conformant and naive.
