It’s just like money. There’s plenty of dollars until a critical mass of people decide that they want those dollars physically in their hands. Then, there’ll be a run on ATM machines.
The government printing presses of late are mostly just zeros added to computer accounts. They aren’t really printing more dollars.
Same with gold. Most good transactions are paper certificates in lieu of gold. That works just fine unless you get a critical mass of people wanting to actually hold their property.
This is why goldbugs believe that gold isn’t gold unless you take possession.
I must be a gold bug.
