No, the problem would be lack of knowledge and infraestructure.
Like the lack of knowledge you have about modern industrial farming.
If you "farmed" with primitive methods today billions would starve, because your crop yields would be shit. Your plants would be weak and they would be eaten by locusts or other pests.
Modern industrial scale farming exists solely thanks to modern pesticides, fertilizers, roundup, mechanized harvesting, and all sorts of things that enable bumper crops to feed millions of people.
Entire regions now do farming thanks to fertilizers otherwise their soils wouldn't even be able to sustain it. For example the cerrado region in Brazil is seeded with phosphorus to enable farming there. Otherwise nothing would grow.
Organic, subsistence farming can only get you so far. Homesteading is enough for a small family just fine but you can't feed millions of people without modern industrial inputs. No industrial farming -> Millions of starving people from the cities would pour into the countryside to loot your shit.
