I mean it as a response to your question: 'has gold failed as a monetary good?'

Gold worked up to a certain point of scale for payments, but it couldn't go beyond that. Sure, its price in fiat terms has risen over time - but if you held gold instead of Bitcoin, you missed out massively.

Maybe you're looking at it from the perspective that gold was a success for centuries - I can appreciate that.

But this also ties into the main point I'm making - if something comes along that's somewhat similar as store of value *and* is better for payments, that something will win.
