The gold is for wealth preservation,,,, not the day after a crash to expect to walk around using it like normal money. Your normal human prepping (food,,ammo, etc) should allow you to bridge the gap,,, and then a few months later walk into the new paradigm with wealth preserved via gold.
That said,, there is a certain logic to your position. Though the government can print all they want,, or suddenly retire it to be replaced with a the new Amero etc,,, i think there would indeed be a short period where having a reasonable supply of cash is wise.
The knock of gold that its hard to spend for a loaf of bread, is indeed a difficulty **to an extent**. But the risk is just as real that the buying power of your paper money will evaporate in days or weeks.
The smarter thing is to have the wealth you want to bring into the new system which will replace the crashed one, stored in gold. And have some cash,, for lesser crises,, for minor purchases. But the fact remains,,, in a true crash,,, you should not need to be out making purchases. Thats what your prep work is for.
Very reasoned approach. The organic problem is hardest to plan for. Strategic and tactical plans include all the vehicles for survival. My lesson or knowledge for this great forum remains that we all face truly tragic economic problems.
