In light of the recent surveillance revelations, supervillainy abounds. While I'm sure the status quo is well aware of my identity, I'd like to put a few things in comparison. First, the main issue with warrantless surveillance is that is a rather poor tactic as far as far as terrorism prevention goes. Secondly, it puts a lot of private information at the hands of government and corporate entities which may target certain individuals or groups in the future (even if not today). Third, it violates the principles of due process enshrined in centuries of law, and likewise makes transparency of Big Brother much harder.
Much of PRISM operated in a legal black hole, outside of the regular checks and balances. However, as Robert Heinlein said, "Privacy laws make the bugs smaller." Even if this program is shut down, future projects may well continue. While the cypherpunks are trying to hide and encrypt themselves, the status quo will try to break their codes. However, the symbolic resistance of encryption is still a method of self defense available to most people. While it might not totally prevent government spying, it still can make it harder for hackers and identity thieves from stealing your information.
