Gold is no good as a currency.
Just as there is no point in making buggy whips anymore. Running shoes are pretty popular these days. Paper is pretty cheap so it's alright for currency. Especially the new stuff it's so wear resistant. Trust is the big issue. Who do you think you trust. Make a list, be honest with yourself. There is only one person you always have to live with who you even have a chance of trusting no matter what changes. For everything else you need some kind of insurance. And that insurance has to be cheap so everyone can afford it. Gold as it is valued now is way to expensive to use it as a currency. Currency has to have a material value of zero to have maximum currency value. That's what makes bitcoin a good currency. It just can't work because there's no trust or did you actually find someone else you can trust.
