Why are house deeds automatically made public?

What if I don’t want it to be public? I don’t want someone searching me to find out I have property. Why are some things made searchable on the internet such as birth, death and marriage records?

Nowadays, an advanced hacker and thief would only need one piece of you to make your life miserable.

I’m not sure what a thief can do with a recorded deed, but I’d rather it not be public information.
