Production buildings are now independent private-sector agents: they keep what their output sells for, run only to the demand they can actually sell, and spend that cash on steel and high-tech upgrades when their demand grows. Grid power is a paid private flow between plants and their consumers, and regions synthesise the food their own harvest and the reachable market cannot supply.
Island regions no longer famine: a region with no reachable supplier grows its whole shortfall from energy, and grid power now feeds cities and food before the converters, so a famine never waits on a factory.
