The point is whether or not it happens, as a parable it's validity is sound. Point is, if even if the current government has nothing but good intentions and would never use the information to do anything you don't agree with, and you are in perfect agreement with the current government. There is always the risk of either the government changing or someone stealing the information from the government that could weaponize it in ways you would never want.

what's crazy to me is the people who defend this type of stuff, are the ones that are also terrified of gun registration... because you know if one day a gun ban were put in place, having a list of where all the guns are would make confiscation easy and legal. But they don't realize that it's just as likely for them to hunt people who spoke out against the government, or were the wrong race.. or hell, just possibly see that you have a gun because you took it home on a ring cam.
