First, enjoying food does not imply spending hours cooking food. If you think so, this is one thing your culture taught you wrong. Good food is simple, can be frozen, or even eaten raw. Also, there's no explanation to why one can order chicken wings by phone and have it delivered in 30 minutes but not something healthier other than pure ignorance.

Second, this is a reductionist, naive view of nutrition. There's more to nurturing than swallowing a mix of nutrients. Smell, taste, chewing motion, the brain. If you don't enjoy your food, you don't feel satisfied. If you don't feel satisfied, your organism doesn't work as expected, neither your mood. Food and pleasure are intimately associated, you cannot have a whole human being by reducing the act of eating to an inconvenience.

If you were right, enteral diets (Google what it means) would be completely normal by today.
