It doesn't matter if you are guilty if no one (not even you) knows where you went
and it would take an act of congress to find you, IF they even knew who you were.
Mistakes are often made, even by those with the best intentions. The system can grind up innocent people in all sorts of ways. The more power you give to the system to do this, the more you increase the chance that mistakes will happen with increased frequency and severity.
Malicious individuals exist within every organization. Even if you trust the government and big business as a whole, do you trust every individual working for them that handles your private info? The potential for abuse, stalking, blackmail, harassment, and other bad stuff exists and is real.

So what?
This doesn't have to be a constitutional issue, and not everyone here is an American. The issue effects eveyone on planet earth, not only Americans. And even for us Americans, there are many issues and problems that need to be addressed by society that have nothing whatsoever to do with the constitution.
The constitution doesn't say anything about drunk driving, to pick one example, but its still something illegal and generally recognized as bad for society.

The U. S. Constitution contains no express right to privacy. The Bill of Rights, however, reflects the concern of James Madison and other framers for protecting specific aspects of privacy,
The meaning of the Ninth Amendment is elusive, but some persons (including Justice Goldberg in his Griswold concurrence) have interpreted the Ninth Amendment as justification for broadly reading the Bill of Rights to protect privacy in ways not specifically provided in the first eight amendments.
