Food, water, shelter, and healthcare are not things one chooses to buy, but things one is forced to buy to survive.
To buy these, you need money. To get money, you need a job. You also need enough money saved up to survive after you can no longer work a job.
To get and maintain a job you need to buy some other things. Exactly what other things varies by job and climate, but in general: clothes, transportation, phone, electricity.
That’s a lot of things that you cannot willingly choose not to buy if you want to live.
