There is no such thing as decoupling when there is a cash equivalent. For example, in the US a lot of welfare funds are handed out in the form of food stamps. This has created a secondary market in food stamps where people sell them to get cash. Also, the mere fact of having the food stamps frees up funds for other things where the consumer can spend more on "non-essential" goods carrying the inflation with it.
