In my opinion it is much more viable to stop a government from abusing data than to stop the government having access to the data. Some biometric modalities like fingerprints, DNA and face images are quite literally "broadcast" by everyone. In many cases, government access to certain data is not a problem if you can trust the government. If you can't trust the government, you have a bigger problem. In the case of knowing who is which ethnicity and lives where in the African context, you can easily construct a scenario where they could round up a particular ethnicity. Or they just ask the locals. In another scenario, if Group A is directing violence towards Group B, the government instantly knows where to send forces to stop it.
