This man may be expressing his views on life, thinking that life revolves around basic needs and daily chores. Tea, rice, oil, salt, ginger and vinegar tea may be the metaphor he used to describe this kind of life, which means that he thinks that life revolves around these basic items and needs, but it doesn't necessarily mean that he has to cook by himself.

Maybe this man is not interested in cooking, or doesn't want to cook, but he still thinks that other people should be able to cook for themselves and their families. This view may reflect his attitude towards family and life, and he may pay more attention to the stability and basic needs of family life rather than pursuing cooking skills or food enjoyment.

Generally speaking, this man may pay more attention to reality and basic needs, and have a simple view of life. But his views do not necessarily represent his actions, because he may be more inclined to let others practice his theory.
