[Commentary] In the 21st century, is trying to stay off the radar really possible? The answer is no, unless -- and this is a big hurdle to clear -- you are willing to give up the thousands of conveniences and opportunities that the digital world seduces us with.
If you wanted to be not so much off the grid as off the matrix but still be in the United States, you'd have to be willing to live in a cabin way out in the woods somewhere, have no utilities, spend only cash, grow most of your own food, never, ever, ever get sick and, if you were really serious, break the law by not filing your taxes and being generally unaccountable as a citizen. If that appeals to you then the best of luck to you because it would be, in modern America, very, very difficult to pull it off, and the way things are going, within a few years it will become truly impossible. Why? Because as the recent NSA intelligence gathering revelations demonstrated, if there's some data that might have any bearing whatsoever on national security, homeland security, law enforcement, or taxation, then there's some raving bureaucrat somewhere who wants to pigeonhole said data just in case. Once those little nuggets of data have been collected, collated, and corralled you are in the matrix, er, system forever.
