The problem is that they store all this data. Can you trust all future Governments of the US and their allies, for the whole rest of your life?
This is not a hypothetical - it’s actually been a serious problem for groups of people. For example, census data voluntarily filed by citizens to probably then trustworthy Governments was used by a later regime that invaded to identify which people to exterminate in the holocaust.
Then there is the problem of leaks. Sure you might trust the Government with that data, but what it it’s hacked by a criminal organisation, or other governments etc.?
