I strongly encourage folks to gain individual means of production now and prepare to barter with folks for goods and services that may soon be only attainable through official channels by suffering intolerable surveillance and invasive and life threatening medical abuse.
Cash will not feed your family if you can't spend it. Guns won't protect you from regulations. Stockpiles of beans and rice will run out.
Independent means is the definition of wealth that matters, and it will become the only means of freedom quite soon. 3D printers, aquaponics, solar, and other distributed means of production are the key to our continued felicity, prosperity, and liberty.
Good point bringing up aquaponics. Most people who would other acting are probably already thinking of solar and 3D printing.
