..., I would rather be in my position - happily FIREd and not working 2,000 hours in a year and doing 5-10 hours of work to cut costs than the other way around. Trust me - one day of "work" beats 200 days of work a year. :) If that's being beaten by inflation I will happily take the loss.
I get all the concerns expressed in this whole thread...I really do. But in the end @FIRE 20/20 expresses my truth which is that money is not what's important to me. Controlling my time, setting my own priorities, and doing what makes me happy everyday is what I want. And if I have to cut spending or implement more optimization or whatever, I can do that. What I couldn't do is get those days back if I had chosen to work one more year (or two or ten). I'm not criticizing anyone who did/is doing that, but that's not the choice for me. The last 15 FIRED months have been glorious, and I wouldn't trade them for any amount of money!
All this feel-good stuff about being currently ER is well understood, that is why we are on a FIRE forum pursing FI and ER, and we all ultimately have to determine our preference for OMY of work vs. ER. I'm here to get exposed to new ideas. I'd love it if, somewhere in all these 'reassurances that 4% SWR baked in inflation', that folks would actually discuss where they are seeing unexpected benefits of ER to offset inflation that they would otherwise have missed had they been working.
It's pretty obvious to me that getting COLA income during times of high inflation and continuing to DCA and not spend the retirement 'stache during a market swoon are going to make my FI stronger (e.g. my 4% SWR will start when CAPE is lower, I'll have more fat in that 4%SWR budget and/or I'll get to a bulletproof 3.5% SWR, etc). But I'm here for the ER folks to drop some inflation beating benefits specific to being early-retired.
I guess the point is, getting a couple years of ER in my 40's at the expense of worrying about FI in my 70's isn't a good trade-off. We won't know that outcome until it's too late, but there is good evidence that the kind of conditions we are currently experiencing would lend itself to FIRE troubles. Compounding on this, I'm pretty sure Social Security will be a shadow of what it was for current beneficiaries. So I'd love to get some new information to add to the reassurances that, say, inflation in ER isn't a problem. I'm pretty sure none of the FIRE blogs or fora talked about being prepared for high inflation, but that would've been pretty awesome to see a blogger 'inflation prepping' in 2020 - buying their forever house in cash with solar panels, 10 years of food, a new EV and a set of spare tires...
Just hoping to move this conversation forward again, the 'being-ER euphoria' from the last decade has been done to death. Inflation was low, market returns were great, and worrying about the 4% rule was a waste of time. FIRE was the way to go. We got that message. Times are different now.
I think so much of this depends on the kind of FIRE you plan for. While I'm reconsidering now based on outside factors, my FIRE plans currently include a fair amount of travel. If high inflation or a recession/depression kick in, travel will be one of the first things to go, or be scaled down. Will that be a cut that actually affects my happiness or QOL? Yes. (If not, then it shouldn't be in the budget or plans at all.) But it will subtract less happiness from my life than working another year, or having my spouse work another year would have. So it still makes sense to plan for it in the budget, but also to quit slightly earlier, knowing its fat we can trim if things are looking good.
Similarly, I'm intentionally cultivating a side hustle that doesn't bring in much, but is something, and yet it's not unpleasant and entirely flexible. So I won't mind keeping in FIRE. It's also something I could pretty easily do when I'm 75, if necessary. (Meaning, it isn't physically taxing.) It's also somewhat scalable, and while i know that in down markets, everyone will be looking for work so it's a bad time to be doing that, it seems realistic that I could hold on to it and perhaps even expand slightly. But it's ~10-15 hours a *month*, so it certainly doesn't feel like I'm back to having a job. Would my life be infinitesimally better without it? I suppose, since if I had a $100m, I wouldn't do it any longer. But it that difference is so tiny that it is well worth doing this, compared to another year (or even a few months) of FTE.
These are the kinds of things I consider to be inflation (and down market) hedges. Sure they are sacrifices in that in a perfect world, they wouldn't happen. But when I compare them to working FTE longer? Giving up some travel for a few years and doing a pleasant side hustle for a few hours a week? Easy. I think these are the kinds of things people should be looking for.
You say that a couple FIRE years in your 40s isn't worth worrying about money in your 70s. For me, a couple FIRE years is worth having to make some cuts to the luxury items we hope to have, or putting in a few ours of WFH every week or two. That's not a good trade-off; it's a fantastic trade-off.
Also, while FIRE blogs don't talk much about inflation, they do talk about bear markets and recessions. And it seems most of the answers are the same. When markets are down or costs are up, you flex the things that are flexible.
