I actually don’t see anything wrong with planning for extreme “what ifs”. As long as you also attribute the probability of it coming true in your planning as well You should also plan for “what ifs” at both end of the spectrum too. Not only should to plan for the Fed completely failing and you’ll get major deflation, but you should also plan for the Fed completely failing to control inflation and we’ll see a repeat of the 70s/80s. Obviously, either of those scenario are very unlikely to happen, but it’s not impossible. If you plan for it, then you won’t be blind sided and follow the heard off the cliff.
