All the financial systems before the present one were based on gold (and, to a lesser degree, silver). So, if the current financial system collapses and the world population's faith in the financial system must be restored, what do you think is the most likely outcome? Not 100% guaranteed, of course, but highly likely. The fact that central bank's all over the world continue to hoard, and buy, gold makes this rather obvious. The level of ignorance and the lack of critical thinking on this︀ thread is simply astounding.
I do not own much gold myself, so I have no︁ dog in this fight. But this stuff is rather obvious. I own one of the︂ few things better than gold: income-producing farmland. Farmland, unlike gold, is diminishing rapidly and it︃ also earns an income. And food prices are very sensitive to inflation. But most people︄ cannot own a farm. So, gold is the next best thing -- as insurance against︅ geopolitical and financial instability and inflation. And unlike a farm, it is easily transported.
