Excellent article! Thank you.
My 3 cents. I think all financial investments are a poor form of security. I feel like we would be much better off investing our time and financial capital equitably in building all 10 forms of capital! If there were to be an economic crisis, gold, silver and money would all be next to worthless. If food distribution channels and energy plants were to be disrupted. People would starve, freeze and it would be disastrous. No amount of money can buy you food if there is no food to be bought. That is all to say about the security of mediums of exchange vs the security of other forms of capital.
Having a food forest in your own backyard provides way more security than gold or bit-coin (though I also have a fair amount of both :) )
