Americans willingly stopped farming their own food because it's more economical for farmers to grow in bulk and sell for a little profit. The only way to make more people farm their food would be by government compulsion.

Why would you want that?

And any time they spend growing their own food is time they don't spend on some other economic activity they're obviously better at.

Why would we want that? Because the food is substantially better quality and healthier.

And the time? We do this in our spare time outside of full time jobs. But you're right, it does cut into our Netflix, tv, YouTube, Facebook time.
