If you want another, more benign, example, look at American military bases. You've got base housing, base grocery store, base furniture, base movie theater, base bookstore, base clothing store, base restaurants, base barber shop. You are issued things like housing. There's a pecking order based on rank. If ranks are equal, there is an alternative barter economy based on who owes who favors (instead of money). Although all your needs are provided for (at massive cost to the taxpayer), it isn't a happy way to live.
