Most farmers lived on farms. They actually did have to make a lot of their stuff themselves. Yes, you had a large family, but you needed that to be able to survive.

>Once you have as much as can reasonably be consumed before it goes bad you are done. If you catch a deer within 30 minutes you are done. If someone else did well fishing then there is no value in going hunting at all.

You would salt and preserve the meat/fish and consume it in the future.

Imagine how you would live, if you could only buy metalworks from the store. Basically everything else you'd have to make yourself.
