Isn’t it possible that gold has already gone through the roof? I mean, really there’s no way to know. Lots of people say it’s about to go through the roof, but if they were so convinced, they’d be putting their money where their mouths are.
Pragmatically speaking, supposing that the SHTF, what are you really going to do with a .5 oz of gold? You’d be better off to stockpile Levi’s jeans, whiskey, canned food, etc.
As long as you’re a debt-slave (especially high-interest, uncollateralized debt like credit cards!) it doesn’t make a whole lot of sense to buy gold. You’re still accruing interest on the debt at a pretty good clip. I know people who have $20k in debt but say “I have $5,000 in the bank”. Well, kind of. But in reality, they have -$45,000 on balance.
$1,800 worth of debt is almost zero. $1,300 of debt is even less. Sounds like you could pay off the balance in full in a few more weeks. When you’re out of debt, you have all of your net income to dispose of as you please. Fewer obligations, fewer bills that need to be paid, etc., and you can start taking advantage of things like “compound interest” working in your favor 
My wife and I have been aggressively paying down bad debt (credit cards from college, honeymoon, wedding, etc.) It sucks and it’s painful to piss away $1,000 a month to pay for beer that you bought in 2005, but as soon as the last payment is made (November, probably) we see two things happen:
-
We no longer write a $1,000 check to credit card every month
-
We have $1,000 extra in our bank account every month.
That’s a $2k monthly cash-flow swing in our favor. Your example may not be extreme, but the principle still applies.
From there, you realize that you don’t need a six-figure income to be wealthy or to enjoy your life or to go on vacations - because you’re not pissing away money servicing old old debts. And if something bad happens, like say you lose your job, you don’t need to worry about “How am I going to make the minimum payments this month” because you don’t have any more obligations.
