I think you have it backwards.

Practical preparations for known, expected and understood short and mid-term situations are not likely to interfere with less well understood, less probable, possibly more extreme and long-term situations.

Generally I have found the more a person or group concentrates on the less probable and fringe possibilities the less likely they are to have real and practical preparations in place and ready to go for the short-term situations that everyone will be facing. Things like storms and blizzards.

A friend recently spent a bit more than $500 on radiation meters and KI but his family doesn't have even a three-day bag. Their important papers are scattered. They always eat out so there is little food in the house. There is no reserve of water or provision for obtaining, storing or treating water. When his kid fell down his wife, a nurse, didn't have enough on hand to produce even a simple bandage.

Preparing for an imaginary and unlikely mega-event he has failed to prepare for things that happen every year. Last storm that came through I gave him a flashlight and spare batteries.

I have noticed a lot of guys in the same boat. Bomb shelters, radiation meters and guns maintain their interest and get the vast majority of resources. Batteries and and bleach and toilet paper are just too mundane to hold their interest. They can see themselves wearing their MOPP gear and heroically fighting off villainous marauders amidst the fallout and it is a role they relish.

Chemical toilets, primitive hygiene; living off canned goods and bottled water for a fortnight; practical survival and preparations; are not so heroic. They are virtues of bean counters, list makers, shepherds; servants to friends, family and neighbors. Much harder to be heroic filling these rolls. But much more practical.

It reminds me of boys playing cowboys. They are keen to play the shootouts against the indians or rustlers or, given a mature bent, the romance and wild times of going to town. But kids and young men seldom play out the 100 hours a week riding drag. The long hours. Working in the heat and dust and rain. The lousy food. The monotony and boredom. The stuff that makes up 99% of what it is to work cattle.

If anything I see the focus on the possible adventure heroics and highly unlikely situations of mass collapse and apocalypse as being a detriment to practical, mid and short-term, real-world preparations. Not the other way round.
