Buy large property, create an anarchist commune, build Earthships and similar housing out of sustainable recycled material, setup public gathering spaces, spa areas, perhaps stuff like rooms for artists, musicians, workshops, etc. Grow weed, shrooms and veggies, have some animals living in relative freedom and perfect health.

Ensure everything is weather proof based on location's projected future climate, build water/heating/energy infrastructure (solar, wind), offer each building as rent-to-buy, keep growing the community and make sure to plan for the day the government gets scared and sends in their death squads.

Basically something like Kristiania in Copenhagen but bigger and more focused on sustainability and land mass, so probably outside of major cities.

Addendum: Would be a good idea to make it impossible to have this grown into an insane religious cult though. 🌚
