By sovereign do you also mean a prepper/hoarder? Or do you barter?
Money is a vastly superior tool for trading. Unless you have all the goods and services you’ll ever need I fail to see how sovereign people don’t need money.
Discussion
I do as much as I can as a survivalist before prepper/hoarding.
I barter when possible.
Have used all sorts of money when I can’t make something on my own.
v4v work (labor) is mostly how things get "paid" for.
Yes I still do use shiny metal rocks and worthless paper.
