Unfortunately, when it comes to government, ultimately we get what we collectively deserve.
Statistically, individual privacy has little or no value to most. The majority simply does not care about it. They have never given it a second thought. The true value that an individual places on his privacy may be seen by noting all of the things people will give up personal data for -- these offers usually use the word FREE which in these cases implies no value. Most think nothing of giving up personal data in exchange for a FREE mail in rebate. To them, their own address, phone number, email addy and other data have no value. Their privacy has no value to them -- therefore, it will go away.
I'm all for the encryption of personal data and personal communications. (Nearly everything going in and out of this computer is seamlessly encrypted and decrypted as I use it -- including this web page and this individual post.) It's not that I'm doing anything illegal. It's not that I've deluded myself into thinking that the government can't read my traffic. They can. I do it simply because I don't want them to be able to do it for free. If they want to read my communications, fine. They may explicitly decide to expend the resources to do so. The important thing is that they can't just scoop it up en massse with 300,000 other web communications and scan them all for free.
History has shown that abuses will always happen eventually if there is any opportunity. Nearly all email and web traffic is sent 'in the clear' and may be read by any government or individual but privacy is really of no concern to the vast majority.
