Depends on the situation and the attacker. If its a common thief/gang who wants to steal your coins, then privacy and anonymity are the prudent approach that will better protect you and your family. If its the govt, then being public and open is the safer approach, otherwise you are only hiding from the public who would support you. 

However, in any situation you should be armed, trained, have a security system with cameras, and have dogs, imo. 

 Good point.
