Do you prepare for the most likely threat, like this man faced, or are you preparing for Red Dawn?
Preparing for the worst possible scenario isn't really an end unto itself. If you prepare for the worst case, mentally and physically, then dealing with the more likely case becomes a simple matter. If you're prepared for Red Dawn, then you'll be able to respond to a home invasion with a calm mind and a clear plan of action.
It's just like any other skill. When I was becoming an EMT we trained for mass casualties, for extracting people with shattered spines from equally shattered vehicles, for treating gunshots, for delivering babies in a tent at the top of a mountain, etc.
In reality, these situations didn't come up very often. In my time I never dealt with a gunshot wound, I never delivered a baby, I never arrived on the scene of a five car pile-up...
Day in and day out it was bandaging fingers for the doctor to stitch, splinting broken ankles and trying to calm people down whose injuries weren't nearly as bad as they thought. For me, it was routine simple stuff because my preparedness was well above the level demanded by the situation. I had a 'Batman belt' of medical supplies, I had an entire ambulance with every medical gadget and drug you could imagine, and all of it was there for that one in a million chance that the really bad thing might actually happen.
If all you ever prepare for is a single intruder home invasion or a three day power outage, if those events occur then you're operating at the absolute limit of your training and readiness. You're very likely to be on a verge of panic and without the confidence that you know you can handle the situation. If you're prepared for something much, much worse than what's likely to ever happen, then the lesser events are less likely to overwhelm you.
I do agree that the modern tendency is to replace skill and ability with gadgets and gewgaws. People replace $1500 worth of ammo and range time with a $1500 scope and tell themselves they can shoot great now. They replace proper medical training with a "MilSpec EMT Backpack" and just assume that if they get hurt there will be something inside to fix them.
At the extreme, they buy a gewgaw for every possible contingency and carry them all with them at all times. Those people are not prepared for anything, they're hobbyists with a lot of money to throw away and are no different from the Honda Civic crowd with the spoilers and running lights and custom exhaust who have no idea how to drive in anything other than normal highway conditions.
