Ask HN: What could be done to create low maintenance, sustainable living?

Hi HN, there is a lot of talk on hn about the government providing basic income, but my thought has always been in the future people would create a low maintenance, sustainable life style...

examples might be: owning your own home, owning solar panels for power, owning an electric car, using 3d printers for stuff, growing your own food (with robotic harvesting).

what other technologies or ideas might create help create an independent sustainable future? why doesn't this idea have much traction?
