I think there is room within Mustachianism for one or two minor splurges that help keep you happy. As long as you're not going whole-hog on multiple fronts. For example, DW and I spend more than most Mustachians on food (although probably still less than most middle-class Americans), and I don't even want to tell you how much we spend feeding the birds that make our home-bound existence worthwhile. But we eschew expensive cars, expensive entertainment, restaurants, big cable TV packages, I phones, new clothes, etc., etc. Most "normal" people stand with their mouths agape when they find out how frugal we are. We are saving a huge chunk of our income, have reached FI, and I'm planning to FIRE in January. Works for us.
This is definitely the case. The three main "required" living expenses are housing, transportation, and food. If you absolutely nail two of the three, and do pretty well on the third, many other "splurges" just turn out to be noise. If you live in a house that costs $400/mo less to own and maintain and $200/mo less on a car to own and maintain than your buddy Mr. McSpendyButNormalSeeming, you still come out way way ahead even if you're splurging $100/mo on something objectively stupid.
But that doesn't make the objectively stupid thing non-stupid, it just makes it "not matter" as much financially. The problems occur when that $100/mo is really eight different things that each cost $100/mo, or if that $100/mo doesn't include other gigantic expenses that accommodate that $100/mo interest/hobby/habit.
I'd say what truly makes something Anti-mustachian (there's that no true Scotsman fallacy again) is inefficiency coupled with a lack of badassity.
For example, we have dogs, which one could say is anti-mustachian. But we don't spend a buttload on dog food, grooming, vet visits, etc. My GF bathes/grooms the dogs herself, I roll my own raw dog food (including cutting up multiple free wild venison carcasses in addition to buying for cheap in bulk from meat suppliers; averages out to less than $1/lb these days for dog food), and we keep them healthy to mitigate vet visits the best we can (obviously, dumb shit still happens sometimes). We don't pay for a dog walker or anything like that, and we didn't buy a hilariously expensive large vehicle "for the dogs." Everything we can is in-sourced.
Also, we eat fancier food than many (though probably fairly similar to MMM himself). But it's all made at home from scratch every day, and we buy in bulk/optimize our sources/shop the sales. I'd say we spend more than the median Mustachian couple on food, but still less than the median American couple.
Also also, our house is a third the cost of most of my co-workers, and our (single car for two people) car is about ten years older than the median in the parking lot at work. Oh, and no kids or plans for kids, but I'll just leave it at that.
