The article you've linked paints it as life-style, entertainment - rich people hobbies, which is different than doing it because it's more productive.

People will "trad-code", but not because it's the productive thing to do.

It's fun, and it's serious - keeping heavy horses and bullocks, feed, breeding lines, etc isn't trivial - and they are worked.

The serious side is simple enough, local food security - when there's no diesel to seed and harvest with there will be no export crops from here to feed millions across the planet .. but we here will still have smaller crops via animals for our food.

I'm literally in one of the most isolated parts of the globe, WWII, COVID, shortages via Iran clustf*ck, etc have real impacts and we plan to ride those out, like floods, droughts, cyclones, etc.
