I don't see how that applies here though. You are paying for all the services you consume. Someone that eats out all the time contributes significantly more economically to the restaurants in the area compared to someone that lives in the area permanently but always cooks at home.
But those services can't exist without other people owning all the equipment and land needed to provide them. Once your quest for minimalism turns into externalizing the things you need to survive (instead of getting rid of things you don't need) then maybe you have lost the plot.
I don't get this line of reasoning. The average person doesn't grow their own food, everyone has already externalized the things they need to survive.
The difference between going to the supermarket and then cooking your food vs going to eat at a restaurant is just relying on the restaurant existing.
The restaurant existing relies on people visiting it, so by visiting it, you are helping the restaurant and they are helping you. I just cannot agree that this lifestyle is "subsidized" by society. Enabled, sure, but modern lifestyle is enabled by society and that's generally a good thing.
