As a thought experiment, picture:
the minimum amount of clothing you need for the rest of your life if clothing was scarce. IE you're wearing shit until it falls apart. Probably a couple hundred pairs of socks, half that for underwear, a dozen good pairs of pants, same with sweaters. A few dozen Tshirts. 4-6 coats both heavy light and for rain. 4 or 5 pairs of shoes that are re-soleable. Picture it laid out in front of you on your bed. It's a small enough amount that you could get it right now for a couple or few weeks wages at any full-time job.
Now consider that a man can live healthily on just potatoes. Add sweet potatoes and lentils and you can eat healthily all year round for a very minimal amount of money / resources. It _could_ all be grown in your backyard too, but for the sake of societal efficiency it wont.
Finally consider the heat and electric required to have you as a single person in a 200sqft room with a low-wattage laptop and a bare minimum hvac for heating / cooling. That setup could be run on the most modest of solar systems, including a low-wattage chest fridge.
All that to say, the base-level for resources required to keep an adult man alive and content in a first-world environment are strikingly low. This is the base-level. Anything ahead of this will of course require more resources but we shouldn't pretend it takes a monumental effort to keep a man alive and thriving when today's level of automation and tech availability are considered.
