The real physical gold market is very small. I'm not talking about the London paper market which is misleadingly called "physical."

So how come ETFs around the world are able to suck in billions and billions of dollars of investors money and always have no problems buying the real physical gold they need, despite the competition from ordinary investors around the world and much larger investors including nations, without sending the gold price absolutely skyrocketing?

Maybe it's best not to ask these irritating questions?
