@matrix There should also only be communal toilets in neighbourhoods, people should not have toilets in their homes. Along with the kitchen system the plumbing would be simplified, water consumption would be more controlled and of course communal bonds would be strengthened. There should be a selection of toilet paper, provided via social credits and nfc identity cards on the spot, so good citizens are rewarded. Finally, the waste should be centrally recycled into water to be given to people in the communal mess halls and solid compost being used in communal greenhouses.
