So what happens when you are unable to do work that pays enough to survive?
I live in an area with very poor populations in terms of money, but rich in terms of heritage, culture, resources, and morality and work ethic.
If you need fruit, you harvest from the orchard. If you need veggies, you harvest from the garden. If you need meat, you harvest through hunting or livestock slaughtering. If you need anything else, you process your harvests into usable materials for trade and barter or monetary sales.
In other words, you produce or you die.
But don't you know that there is not enough room for everyone to have a personal (even communal) orchard?
Or that there is not enough game in the woods to feed humanity for one week?
Or that people started settling in cities where there are no orchards thousands of years ago?
Or that there would be no computers or internet if everyone lived only off their land?
And the part that produces all these nice technology for you is driven by cities with workers.
And the socio economic environment in cities is completely different from 'living off the land' and people can realy be dependant on someone providing work or even welfare.
