You think that the majority of people actually know how to do those things successfully in the absence of modern logistics or looking up how to do it online?

I have a general idea of how those things work, but successfully hunting an animal isn't something I have ever done or have the tools (and training on those tools) to accomplish.

Which crops can I grow in my climate zone to actually feed my family, and where would I get seeds and supplies to do so? Again I might have some general ideas here but not specifics about how to be successful given short notice.

I might successfully get a squirrel or two, or get a few plants to grow, but the result is still likely starvation for myself and my family if we were to attempt full self-reliance in those areas without preparation.

In the same way that I have a general idea of how CPU registers, cache, and instructions work but couldn't actually produce a working assembly program without reference materials.

I mean before you stave to death because you don’t have food in your granary from last year, you don’t even have the land to hunt or plant food so it’s not even relevant
