At least in the US it's not even a good method either. Own a house? Boom, your information is publically available and you won't be able to remove it without a court order, which in most states is impossible to get. In most states, you don't even need to own a house, decide to vote? You information again is publically available. Tie your real name to a single account to purchase something, and you are trackable. Want privacy? You'd need to remove yourself from the internet, dump your phone, destroy your ID and work underground for cash. We can push against iot, and people have been forever, but at the end of the day the government will always they have a vested interest in being able to identify it's citizens.
