>>1705879Not OP, but things I would practically like to be able to produce on a homestead? Location dependent obviously, but ..
Forage/Pasture/Hay
Livestock for meat/milk
value-added animal foods like cured sausages, cheese and butter
fruits
honey or syrups from trees
some vegetables for both human consumption and livestock, carrots, potatoes, beets, brassicas, etc
using a root crop seed mix and allowing pigs to root them out at maturity to condition garden beds.
Also a forest habitat with Oak or Chestnut for livestock forage as well..
I think you're right..it's not reasonable to think you can be entirely self-sustainable unless you make up for the loss of technology with sheer amount of land and natural resources.. I would like to produce all my own electricity, but like you said, practically impossible to do in perpetuity without outside inputs.
I could see, if I wanted to be really OUT there in the middle of nowhere without electric hookup, maybe investing in some low-tech battery based stuff that could be charged from some solar arrays or wind or water.. And maybe a big LPG tank and a generator.. Could I live without a washer and dryer? Probably. Couldn't live without lights at night..
Could maybe, if the climate was right and I perfected some good food storage methods, get by without refrigeration.
Always need cooking/heating fuel.. I've heard 10+/- acres of forest is enough to provide in perpetuity heating wood for a single family home.. Seems like a decent enough rough estimate.
Also it's probably easier in most contexts to import staple crops like grains..
You can bet I'm still drinking coffee, even if i'm in Canada.
