Dicey, I only half agree with you. Mustachians for the most part do seem to be much more flexible and resourceful than most. Additionally, most mustachians seem to have either been through pretty significant market drops or are pretty mentally and emotionally prepared for one. There do seem to be a large contingent of newer/less experienced mustachians who may not be aware of risks such as this. Addressing this as a risk, and discussing different ways to mitigate it, is definitely a valuable discussion.
Well, I guess my glass is half full then.
I think i do not disagree with you, but I think I do disagree with your approach. Ditching the 4% rule is extreme. Calling this a risk, without proof just doesn't make sense. It just is not a significant risk. If X happens, you do Y. If X+1 happens, you do Y+1, so to speak (this is fake math). The 4% rule is tested (using real math) across all market conditions between 1926 to 1976 in the US Stock & Bond Markets. It also applies to average people doing average things. Mustachians know how to live on less, earn money on the side, etc. We can roll with the punches, and be flex if we need to.
You seem to think that it only works in perfect conditions. Learning how to be a mustachian IS mitigating the risk. Telling "young mustachians" that the rule should be ditched is not doing anyone any favors, IMO.
From Investopedia: Bengen concluded that even during untenable markets, no historical case existed in which a 4% annual withdrawal exhausted a retirement portfolio in less than 33 years.

Now, if you plan to live in retirement for more than 33 years, to assure success, you can do a number of things, including saving more, spending less in down markets, keeping a higher % in stocks than bonds, etc. What you shouldn't do is say the 4% rule should be "ditched".
I also agree with Pizza Steve's point that a lot of this scare tactic shit is spewed by the financial industry. They scare you so you will buy their expensive products. Real mustachians don't fall for that crap.
