To clarify: let's say several hundred, or even thousand, people reclaim a part of a city and declare it a free town (no private property, no money/currency, no taxes, institution of a gift economy -- something along those lines). How can this community continue to acquire potable water (assuming this community is nowhere near bodies of water that are even close to safe to drink)? Should it just make at least the one exception of giving into the state and paying for water to be pumped in? Is this even a feasible situation?
What did/do Christiania, the Blitz, Ungdomshuset, and other free anarchist communities do for water and sewage treatment/access?
Sorry if this isn't 101 enough!
