But it's like we're arguing that farmers can't survive that, when in comparison, they are the best positioned to do so.
They ARE best positioned to do so, but it wouldn't be easy nor guaranteed.
Like I said, my family HAS a farm. I've seen that pantry and the personal garden.
The garden can provide a lot of things, but it can't provide EVERYTHING. That's why the pantry exists. And after a year or so of post-apocalyptic living, that pantry will be sorely depleted.
If they only have sterile seeds to plant- which is the current norm- they've got only one extra year or so of harvests to stretch out their food supplies. If they don't have livestock, or are not near another farmer who does, farmers in certain regions will have issues getting enough protein.
Yes, over time, wildlife will return to formerly cultivated land, but that takes TIME, the one thing they cannot do much about. That wildlife will be sparse until fences deteriorate and the native plants really start to reclaim the farms.
And hunting them will become increasingly difficult as ammo gets used up. Make your own? Sure, if you know how to make gunpowder from scratch using local supplies. What about bows or spears? Great, if you know how and you have trees big enough to supply you with the right sizes of wood. But you live on a farm, so most of the trees on your land have been cleared and those that remain are probably functional- fruit or nut supplying etc.
My point is that even though they're in the best position to survive, long term post-OOPS survival on a farm in a modernized country would still be long odds.
