I think you start with a kind of non-profit member-owned "general automation corp." that supplies a level of basic QoL: clean water, food, shelter, clothing, energy, internet, medical, etc. per-member, at a set rate, say US$300 per month. That is, you pay in $300/mo. and that covers your rent, food, utilities, health insurance, etc. Over time the rate you pay falls to zero and remains there for the rest of your life.
The task of the corporation is to supply the above goods and services efficiently, in environmentally regenerative ways, while meeting or exceeding minimum quality standards.

It's kind of like a new economic regime developing within the old one, the way a crystal precipitates out of a saturated solution, eh? A sort of phase change?
