The federal government could maintain a central database containing the DNA of every citizen. Submitting a sample might be incentivized by barring people from, say, receiving social security, disability, government backed mortgages and student loans, food stamps, tax refunds, and other federal benefits if someone doesn't comply.
The National Institutes of Health, the Centers for Disease Control, the Central Intelligence Agency, the National Security Agency, the FBI, DEA (Drug Enforcement Agency), ATF (Alcohol, Tobacco, and Firearms), ICE, CBP, and DHS (Department of Homeland Security) could then mine the database for insights into disease, epidemics, crime, intelligence, and so many other purposes. Just imagine the possibilities.
