It occurs to me that living frugally requires what, in the business world, you call Working Capital. That is, you have to own stuff in order to take advantage of savings. E.g.
- if you buy groceries for a family, you need a place to stockpile, at least a little
- you need a fridge so your veggies don't rot, which is a waste, OR
- you need sunlight and a place to put plants so you can grow a garden, AND/OR
- you need tools to preserve your produce
- you need transportation of some kind, since few places have grocery stores within walking distance
The more working capital you require, the less nimble you become.
This guy doesn't live as frugally as he could, but he does have lots of flexibility.
Moreover, simplifying your working capital requirements is a great way of saving money and increasing flexibility. E.g.
- you start off being a gourmand, but decide to simplify your cooking. This allows you to sell half your kitchen stuff, and focus on buying cheaper items in bulk (lentils, grain, eggs, etc).
- you collect model trains, but decide you don't love it as much as you love FI. This allows you to convert those into $$ on eBay, free up floor space, etc.
- your 6-month-old is potty trained early, Chinese-style. This allows you to ditch the whole diaper thing. Conversely, though, it makes some things more difficult, since you can't on, well, you know.
So, this house is a very Working Capital-light setup, but that means you have to eat out all the time, find places to stretch your legs and relax, find places to hang out with your friends, etc.
There's give-and-take between frugality and working capital requirements.. the process called "life" can be done any number of ways, and Mustachioed Money Muchachos(as) (sorry, it's forced, I know) are always tweaking the process in a way that reduces working capital without sacrificing important values.
