That's a noble goal, but housing, food, and utilities are all land intensive. With concentration of wealth comes ownership and control of land. Most of what is needed to sustain a person isn't items, but a place to live (limited resource, owned by the wealthy), water (somewhat limited resource, water rights owned by the wealthy), and food (land and water dependent). Even electricity depends on expensive-to-extract fuel (thus available at the whim of the wealthy) or land (for wind, solar, geothermal, etc).
What makes you think that the owners of the land will let you use it? The items that you make aren't worth anything to them since they can make their own items without you.
