Threat models matter because they define the two set points you actually need to function. Your threat model defines your floor. Your minimal baseline that must be maintained or bad things happen. The other is set based on your comfort level and is your midline target. That one flexes. Changes as your life changes. But you need both because without them you don’t have a system. You have vibes. And vibes get people compromised.
If people don’t know where their floor is they can slip up and don’t even realize it. Thinking they are protected walking around with a gaping hole in their system. The tactical baseline need is obvious but people miss the mental aspect of having a target setpoint. If you don’t define that level the default compulsion is to go as extreme as possible. I see people do this all the time. They start with hardcore. Then more hardcore. Keep moving the needle into elite level fieldcraft zone, and then either their cheese completely falls off the cracker or they now have a life that is so rigid it is unlivable. They burn out. They quit.
If you don’t look at the map and figure out where you are and where you need to be you are just throwing random shit at the wall, hoping for the best. People don’t need hope and more is better. They need a system that fits their reality and protects them without wrecking their life. A threat model gives you that.
