> This is impossible to guarantee today. Certainly if you run the zero-day magnets known as browsers, and even if not, there is always some possibility of physical intrusion.

Bingo. Even if you go all-out with security and only browse the web with a pure text web browser through Tor running on a VM that you purge after every use, use full-disk encryption with plausible deniability, fully shut down your computer and wait until the RAM is cool before leaving, inspect your computer for NSA/other implants every time before boot, tape your webcam and mic, never use your real name, and whatever else you can think of, you're just going to go nuts from all the paranoia, as well as from realizing all the myriad ways your security could still be broken (don't forget to check the keyboard for a built-in logger and look inside your case for PCI cards you don't recognize, and hope they don't have any implants that look convincingly like something you'd recognize as yours). Never mind that this isn't a very viable way to do most things most people actually use their computers for, like personal email, online banking, social networking, and so on.
