This is probably something we'll just have to agree to disagree on. To me, gold is a ridiculous thing to base money on. It serves the interests of an elite few at the expense of everyone else, it is impossible to transfer over the Internet without a trusted intermediary (presumably someone with a presence on both sides of the transfer and owning large quantities of gold) imposing high fees and inconvenience on all parties.
There's nothing, in my estimation, good about gold as a currency. It is, maybe, a useful store of value, if you're wealthy enough to store it safely. But, its value as a substance (should you decide to make it into things) is vastly lower than its trading value. So, you're still trading mostly on what everybody agrees the gold is worth, rather than its expected utility as a substance. Bitcoin just removes the fiction that it is "backed" by a useful substance.
In the past, there have been times when gold was fantastic as a store of value. When the Jews fled Poland, Germany, etc. during World War II, the lucky and the rich had some physical gold or silver reserves to take with them. That allowed them to rebuild in a new country, even after all of their Polish or German currency became worthless or was confiscated.
So, that's cool. Gold has a purpose. I understand that. When shit hits the fan in your home country and you need to rebuild, historically speaking, gold and silver were good to have. Why? Because they were accepted for trade the world over and had some kind of value. But, nonetheless, the fiat money economy is vastly larger than the gold economy...and Bitcoin is slightly more gold-like than fiat money, in this instance.
If, suddenly, my government became really oppressive and started spying on everyone all the time and I felt unsafe because the police had become militarized and equipped with drones and tanks and had placed cameras all over the city (umm...wait...that's sounding vaguely familiar...but, whatever, let's continue...) and I felt I needed to flee for the safety of myself and my family, I could take my Bitcoins with me. They'd be spendable or convertable to local currency in almost any locale on the planet. Even if there is no currency exchange operating in a given local currency, there may be individuals who will sell local currency for Bitcoins. And, that's happening more frequently every day, just as more local exchanges spring up.
"Bitcoin could utterly collapse tomorrow and the impact on the markets wouldn't even register. If gold collapsed tomorrow the markets would crumble."
Of course. Gold has had thousands of years to establish a vital position in the market. Give Bitcoin a little time. It's still a puppy.
