You’d be right if people started permaculture in untouched Amazon, but they don’t. Like easily 30%+ of soil in most countries (exceptions aside like Russia or Finland) have been exploited by humans for decades if not centuries. Biomes have been so modified in these places that nature would take insanely long times (in human timespan) to recover. Steading it and directing it with the input of humans can be a great way to accelerate that and get something for humans in return.
