Light farming and hunting won’t work unless something like >50% of the population dies off quickly. Even then you’d still need to have everyone spread out pretty evenly across the countryside, be able to learn how to plant and do it on time. You’d be going back to subsistence farming which is extremely hard work. Fertilizer and fuel for tractors would not be replenished. You’d have to learn how to save seeds, irrigate without power and pumps, eventually how to plow with draft animals. If you aren’t already doing this now chances are you wouldn’t make it. That’s the problem I have with collapse fantasies, you’re either all in now or you’re dead. The safer bet is on working to prevent a collapse since that’s something you can do now that probably has immediate payoff unlike going all in on prepping.
In the UK we only just survived the WW2 blockade, with a highly centrally planned push to expand local agriculture to cover missing imports. Loss of imports forever will kill over 50% of the population, slowly.
The problem with transitioning to draft animals is preventing them getting eaten in the collapse. We'd probably also run out of trees in a few years.
(Collapsists should make more study of WW2, such as Beevor's magnificent, horrifying Stalingrad. Or the siege of Leningrad. Surrounded Soviet civilians died by the millions. And that wasn't a collapse in the collapsist sense, the social, legal and technological order remained somewhat intact)
