These people have been basically right. Over the years, I've said a lot of bad stuff about gold -- how it's a lousy currency, how it's just a rock that shouldn't have any value, how love of it is primitive and irrational, how it has no justifiable basis in the economy.

But I'm changing my mind, and it's all due to Donald Trump.

The other day, Timothy O'Brien published a brilliant photo gallery here on Bloomberg View showing Trump's love of all things gold. Trump's stage at the convention was gold-colored. Trump events often feature pretend miniature gold bars. The logo on Trump Tower is gold-hued. And Trump has lots of gold-plated furniture.

What does all this say about Trump?
