We are at a time right now (and also considering, in this thought experiment) a situation where the calculations of whether something is worth our time or not may be shifting.
I make a point of growing only things that aren't dirt cheap to buy, but as things change that cost/benefit shifts. This year when the price of olive oil went sky-high we started using a lot more home-rendered lard and schmalz from the meat we buy. We don't get buckets of it, but we have enough to cook with.

Living on nuts and seeds as your fat source is not feasible, it would take way too much space. This is why people in the past didn't do it.
