There are charts which show the cratering of nutritional content of fresh produce over time so maybe not all goods and services of the past were total crap.
Even if you like modern organic farming, it's carefully regulated to control the risks and environmental costs of using crap. The US National Organic Program (https://www.ams.usda.gov/sites/default/files/media/5006.pdf), for example, requires 90-120 days between the application of raw manure and harvest; only properly pasteurized manure can be used in the months before harvest.
So actually yes I am generally in favour of archaic methods for making food because our biochemistry and the environment has had a lot longer to find equilibrium with non-synthetic solutions.
That isn't to say that we should throw away science and give up 200 years of progress on hygiene, but I also don't believe that packing chickens into their own feces then pumping them with antibiotics and washing them in chlorine is all that great either.
Maybe this solves for food scarcity and I'm all for that being available to other people but I'm perfectly willing to pay a premium on alternatives methods that eschew the use of synthetic products in my food chain.
