I was referring more to the privacy implications of having the government have your DNA on file. Faking DNA; well for that it would depend on how the test was administered. A cheek swab would be reasonably easy to fool, a blood draw less so if administered carefully. This is all assuming no corruption or anything; DNA tests contain no cryptographically attestable proof of match. Any who knows, with DNA based therapies you might find yourself unable to pass a DNA test for yourself in the future.
