Mormon website to find the living among the dead

The LDS runs a website called familysearch.org where you can go to find information about deceased people. Unfortunately, depending where you live, you may very well find yourself listed as "deceased." Furthermore, the website takes public records from the State of California (which ordinarily are not EASY to access), and makes them publicly available to all around the world on the internet. You provide people with personal information like birthdays, addresses, phone numbers, mother's maiden names, previous residences, etc. Occasionally, the information will be mistyped. Yet, why does the one true Church need to make people's personal information publicly available on a website? Perhaps, its easier to baptize dead people if they are actually alive!
