I suppose it's useful if you're really into wild camping. Realistically how often would the average person, even someone living in a rural state, need to catch, clean and cook their own food? How many decades has it been since a significant portion of the population has needed that skill? Probably several generations at least. I bet less than a fraction of a percent of the population lives in a situation such that they don't procure most of their food through purchases of the products of agriculture or animal husbandry. A town has to get very small and very remote before periodic trips to the grocery store become so onerous that it's actually more efficient to set snares or sit in a tree for days on end waiting for a deer to wander by.

I suspect that any scenario in which hunting/trapping becomes a valuable skill for a significant portion of the population is also a situation where knowing how to operate an animal drawn vehicle is also a useful skill.
