I use a similar approach when talking about making something "safe" or "secure". Against what? My front door is locked. That will probably keep out the neighborhood teenagers who might be wandering around looking to grab a laptop off of someone's table. It wouldn't keep out a burglar with the minimal skill of "kicking down a door". But the obvious adult activity inside of the house serves as a fine deterrent in that case. A group of 3-4 armed criminals might not be kept out by a few unarmed people, but sturdy steel doors with heavy deadbolts, barred windows, an alarm system, and armed residents could be adequate in that case. But that wouldn't keep out a military attack force; I'd need my own army for that. But since there's nothing in my home that would be worth sending an army for, that's an unnecessary level of security. The point of security measures is to make it more costly for someone to break in than it's worth for them, while simultaneously making it less costly for the consumer to gain that level of security than a successful attack would cost. What type of threat does an attacker pose? What could they gain access to? What are the potential damages? What's the cost of mitigation? Your chosen strategy should be based on the answers to those questions.
