>it is the best defensive investment around during a deflationary recession. It also preserves purchasing power during hyper-inflation - which is just around the corner.
Please explain how it can be both?
Because it is stable. Even when it fluctuates in terms of dollars, its real value stays pretty much the same, and has done for at least the last 3000 years (actually it has increased during that time, since it buys the same commodities per ounce as it did in 1000 BC, but those commodities are of a higher quality than they were in 1000 BC).
Even though a recession is the necessary cleansing of bad debt and malinvestment accumulated during an inflationary period, the government, fearing the political consequences of the recession, will attempt to "stimulate" the economy. They do this by increasing the money supply and lowering the interest rate, which leads banks to release their monetary holdings.
The result is: more inflation! Which will eventually have to be cleaned out by a recession, which the government will prematurely end with... more inflation! Repeat process until total collapse finally happens, or until someone has the guts to let the recession take its natural course.
Anyone holding dollars suffers from this, because the purchasing power of their money fluctuates in a gradually-increasing cycle. The cycle eventually leads to hyperinflation when the inevitable recession is so deep that they just can't expand fast enough to keep prices high and employment up. The end of hyperinflation is the collapse of the currency, and the obliteration of any savings held in that currency.
Thus, the more of your assets are held in commodities whose real values do not change when the value of the currency does, the less you have to worry about the effects of the boom/bust cycle on your savings and investments. Gold and silver, being durable and portable, just happen to be among the best stores of value, but other things such as non-perishable foods, wine/liquor and tobacco (whose values increase with age under proper storage), and other durable goods are wise to hold.
And why all the sheister gold salesmen would rather have my money than their gold?
For the same reason all the "sheister" farmers would rather have your money than their food, even though food is universally demanded.
Money is a medium of exchange, and because of reasons for which the government is entirely at fault (taxes and other penalties on their use as money plus legal tender laws), it is too difficult to use commodities for every day exchange. So a holder of gold cannot easily trade it for food, clothing, housing, car repair, etc. But he can trade it for money, which can then be traded for those things.
