Cook over an open fire, use straw boxes for slow cooking.

No, please don't use open fires. They are very inefficient. Use a wood-burning stove if you wish. The same amount of wood will now generate several time more useful heat.

Make/buy a horse cart for transport.

IIRC, In the UK, near the end of the 19th Century(ie when there was a well developed railway network), somewhere between a quater and a third of agricultural land was used to support horses. For a very much samller population than now.


The rest are good though.
