Making my own food allows me to eat exactly what I want, in the right amount, made from the right ingredients. It's also more healthy. If you want to get all abstract about it, it's also about keeping a culture of food alive that I grew up with.

I suspect your experience as a digital nomand isn't quite representative, and it probably also has a lot to do with where you're from originally...

So even if you don’t cook often you’ll see 48” ranges, counter depth fridges, and custom cabinetry and islands in high end homes.

It’s not uncommon for a modern luxury kitchen to cost more than most homes across the country.

High end and custom is expensive.

None of them have places that outright lack kitchens, that would be strange. Few of them shop for groceries though - the majority use eg Amazon Fresh

Eating out has overhead that can easily exceed that of cooking, plus it's one block of time.

Eating out is especially time-wasting for snacks.

Food delivery reduces some of the overhead but introduces delay.

Plus, meals that you cook are more customizable. (Ghost and automated kitchens can solve that.)

How rewarding it is to see someone genuinely enjoy something you made.

Once you clear that second threshold, and especially if you have a family, it seems to me that most people prefer it over restaurant-centric eating. Also, if you’re used to prices in major tech hubs, it might surprise you how common it is that a full-time maid is much more affordable than eating out.

Additionally, just because you can afford to eat out every meal doesn't mean you wouldn't rather do other things with your money (e.g. save to retire early).

Of course, if your income is high enough you might not even care about that, but I don't think this website covers such incomes (the highest kitchens I can see are $10k/month) and at that level you can probably pay someone to cook for you.
