Perhaps this is a cultural difference: I don't value efficiency in my life nearly as much as you seem to do. I don't go out of my way to waste time, but I'm perfectly happy to walk through the quiet roads while carrying groceries, thinking about what I've recently read, wondering about things I happen to see on my walk ---such as the Jugendstil reliefs on facades, a very inefficient type of decoration---, trying to identify trees and shrubs, etc.
I also really don't mind taking the time to write this comment, even though there's nothing efficient about communicating like this.
My work and art likewise are not efficient --- elegant perhaps, pretty even; but no artifact I leave behind is primarily efficient (unless it's code that was meant to be efficient only, the worst kind of code).
I used so many words to inefficiently say: I feel that efficiency is rather overrated. I won't ever give up being slow and being at ease with living slowly --- with plenty of opportunity for life to happen by accident.
PS: most of the public transportation stops are 10 mins away from where I live. Even the train. It's 10 mins away by bus ;)
I used to do that when I interned in Germany. The market was near the bus stop and our dorm had limited fridge space, so I’d tend to buy and eat the same day (and rarely cook from scratch). That wouldn’t work so well to feed a family of four that way.
I think part of the disconnect here, though, is that you're associating this process with extra mental overhead, but when there's no extra effort needed to just get stuff you don't need to think about it as much. Forget to get butter? Oh well, you can literally just get it the next day on your way back from the park or the movie theater—or if you really need it right now, you can get it at corner store just a few blocks away at a slightly higher price.
We don't really make lists.
Just the other day I was about to start cooking but realized I was out of butter, so I walked about 5 minutes to a nearby store, got some, and walked back. It would have literally taken me more time and effort to drive to a store nearby with parking than just walking. The same holds for most household basics (paper towels, garbage bags, etc), for which I have about a dozen options within 15 minutes of my home, ranging from cramped bodega-type stores to large grocery stores.
> You rely on cars/trucks indirectly anyway, that bring the groceries to your closest store, and deliver your packages so what's the different
First, basic efficiency of scale when it comes to general impact on the environment; second, as I mention above, it would literally take me longer to do it all with a car than just walk.
The actual minority case is that I'm picking up something in bulk (replacing pantry stock, getting supplies for a party, etc), in which case I might switch to using my car, depending on how heavy or unwieldy it is for a half-mile walk.
Like, come on. No typical two-person household is going through a full package of toilet paper and an entire mid-sized bottle of laundry detergent every three days.
You can also just put every public transportation stop 15mins away from everyones house so you're forced to walk the last bit, look walkable paradise!
