Good points, Wolf.

hmm yeah a tractor would still be nice, because I'm against the use of animals for labor of any kind (drug dogs, plowing fields, pulling wagons, etc) or for a means of transportation. Humanely killing an animal for food is one thing, but putting it into a life of slavery is cruel.

I also feel that the bartering system should come back.

Even if we still used "money", platinum/gold/silver/bronze pieces could be used just like in the old days.
