And we do have real examples of personal (homeless) and regional (Katrina) situations that a bit of preparation for bad times can improve; and the consensus is that pretty much every crisis can be prepared for in similar ways, up to a point of diminishing returns.
So Katrina is a good example where keeping an eye on the news, gas in the car, and even a BoB would have payed off (and likely did for some people). But, out of curiosity, what preparations would you make for becoming homeless? To me, it seems like a fat savings account and investments throwing off capitals gains and dividends are already the best preparation against homelessness and I'm working on both of those anyway.
Yes, in almost every case, this is the best solution; and one that just about everyone on this forum is already working towards. General wealth solves a great many problems, which is why we want so much of it. However, it does not solve all issues. As noted, a crisis can be regional or personal; and the regional disaster of Hurricane Katrina created a great many homeless in a very short order,
many of which did have resources beyond the destruction, but they were trapped into the region by circumstances (for a period of time) anyway. A comparable personal crisis, that isn't finance related, is increasingly rare in our modern world; but not completely non-existent. One such example is; you have funds, but live in a 'rent controlled' area, and a fire causes significant damage to your apartment building, and you find yourself evicted
immediately from your home. At 2am. On Saturday night, and Monday is a bank holiday. Sure, your fat brokerage accounts will go a long way towards "fixing" your personal crisis once you can get access to them; but what about till then? Did you leave your wallet on the nightstand when you evacuated? Or were you at the club, blowing through your carry cash? In this case, a bug-out-bag will do you no good if you didn't leave the apartment with it, but what in my list did I mention that wasn't already useful in your urban lifestyle? What if you keep it in a locker at work? Or a rented locker at the local bowling alley? (That last one I actually did for about 3 years about a decade ago, except the firearm & bicycle) Or keep a foot locker at your Mom's house? Granted, it's difficult to keep an unused bicycle in a foot locker. I mentioned this thread to a prepper friend of mine, and about the aversion to firearms (and probably any other item that the local law enforcement would consider a "deadly weapon") and he mentioned a "monkey's fist", which is basically a small river rock bound up into a rope, and itself has many other uses for the "unintentional urban camper", such as a counterweight to sling your B.O.B. over a tree limb to get it off the ground. The magic about such a weapon is that you don't actually have to
buy one, or even have one when the SHTF; but just know how to make one if the need arises; and it's fairly effective against one or several assailants who are themselves armed with less than a firearm. Three guys with switchblades versus one able-bodied adult with a one pound monkey's fist and a 6 foot leash; advantage one over the three, so long as he is awake at the time.
EDIT: I've discovered this type of weapon is also called a "meteor hammer".
