Is it sustainable to give everyone a boat and all of that stuff though? Is this really any different from a walk through of a big off grid estate with rain collection, batteries, solar, chickens, grains, etc? Just because there is a nice closed loop on day to day resource usage, it doesn’t make something sustainable nor something to strive for to help with climate change.
