It's really not. Think about what this information is used for: It's probably pulled by your insurance whenever you take out a new policy. There's 40 million people in California. If 5% of them change insurance each year (2 million), and that report costs $25 (A reasonable filing fee for a sensitive government document), there's your $50 million right there.

For comparison, it costs $50 for a tax return from the IRS with a Form 4506-T (usually used when getting a mortgage or for other income tax verification purposes).
