Permaculture is a set of ethics based off the principles of island indigenous peoples. Islands are fragile ecosystems, so overtime the ethics were developed to preserve biodiversity. Permaculture takes concepts from indigenous people all over the world to make a catalog of very efficient ways of doing things. You then design to suit your site and individual needs.

There are many branches of permaculture. Economics is one of them, permaculture is all about growing all the food, fuel, fiber and "farmaceuticals " people need in a very small space modeled after a natural forest. Surplus time and products can be traded for money. There is a big push for alternative local currencies, and eventually telling the wealthy they have the wrong paper now.

I am way too indoctrinated to think of many limitations. The biggest one is access to land for the majority of people. Property taxes are pretty hard to pay if you are just trying to live simply in an zero energy input house and off the food you grow. I am more in support of land distribution and waiving of property tax, than universal basic incomes.

I had a miserably failed screenplay that suggested that people should move from the southwest to Detroit. That isn't that practical, because of all the hidden costs of moving there.

I am going to school for parks administration to make public spaces with wild edibles for everyone.
