How do you want to live?
Sometimes it helps me to start with the result I want and work backwards from that. If you could design your ideal society from the ground up not from a policy perspective but on the ground, what would everyday life actually look like for the average person?
How is food produced and distributed? Do most people farm, work in industry, or do service/creative labor? What kinds of homes do people live in, and who decides housing arrangements? How are jobs assigned or chosen or competed for? How is personal property and land treated? How much bartering?
What does dating, marriage, and family life look like? How do people meet partners and raise children? What role do communities play versus the state?
How are conflict, crime, and inequality handled? How do we incentivize for innovation, difficult labor, or leadership? And what parts of our current modern life, if any, would you still want to keep?
