My house is secure and monitored. If I were to acquire automatic weapons that would be the icing on the cake as far as a deterrent goes.
I guess I could lie about owning one to the neighbors but sooner or later someone would call my bluff. Also, these items do have a bit of "collectible" appeal. One of my friends is a programmer and he collects October Revolution period firearms, antiques if you will.
And they will remember...
