Minimal, LOL. What world do you live in? I suggest you pay a visit to Amish country some day and see how people unencumbered with "made up problems" live. Farming and other survival-related tasks are literally ALL they do. And it's all you would ever do without people sitting in offices and factories tending to "made up problems" in order to make your life simpler.
> How is there no time to pursue anything? When I was travelling and not working at all for two years, my quest for survival meant that I had to get food and water
Were you hunting and farming or scraping together a couple bucks so you could head down to a store or restaurant to get food? You would not be able to do that without an army of people in farms, factories, and offices making the whole thing work.
> If there is any hard physical work to do, we have machines for this
Who builds the machines? A bunch of people tending to "made up problems" in offices and factories.
It's very tempting to think you've unlocked the meaning of life after slumming through Europe for a year and a half but you're totally ignoring the fact that there are numerous people working on "made up problems" in tech, agriculture, and manufacturing making it possible for you to do that. You absolutely do not want to revert to an agrarian lifestyle. It's not fun. Realize that some of these "made up problems" in the first world help you actually live a better life than a life of subsistence would.
