I understand. I maybe should have been more specific in my point that I think encrypting everything is the only reasonable defence against such pervasive invasion of privacy. The long term solution is to get to the point where lawmakers talk about encryption, authentication and integrity as things they actually understand. Rather than having people with ulterior motives explain these things to them with snail mail analogies. However, that is many decades off. For now we have encryption and the means to ensure MITM attacks are ineffective.
