I don't think I could fully embrace the Amish way of life but I suspect my local community mostly farmers and ranchers could implement a barter system if we had to. Some of this already exists. We could be self sufficient for things like food, basic repairs, transportation via horses. I am personally not opposed to giving up some luxuries like internet and online shopping if it came to that. I realize some people born into these things perceive them as absolutely mandatory but I did just fine without them for a big part of my life. In the last several months I have not needed to travel more than 16 miles from home. I suppose I could stock up on e-bike parts and solar panels then fall back to horses. Come to think of it, we could build a local warehouse business that stocks up on things not made locally then sell them locally using cash or maybe even implementing a Craigslist-Style barter system over Lo-Rad.
Am I alone on HN in thinking this way? I know I am not alone in my local community, but I am curious how many on HN have thought about this.
